One lift over a live street.
One wind reading you can defend.
Ultrasonic wind measurement at the jib and at the boundary, so lift decisions and the dust and noise record that answers complaints come from the same installation.
Two problems, both answered by wind data
A city site lifts over a public street, which makes the wind limit an immediate safety decision with a stoppage cost attached. The measurement that supports it belongs at the jib, which is the least accessible point on the site.
The same site generates dust and noise at a boundary that is metres from somebody window, and complaints arrive days later asking what conditions were at a particular time.
Both questions are answered by wind measurement, and they are usually solved separately by different contractors with different equipment. One installation covering the jib and the boundary answers both and produces one record.
One building. Seventeen measurement points.
A building measures from the roof to the basement, and from the plant room to the pavement outside.
Wind above the parapet, at the facade and at the kerb. Conditions for ventilation and plant. Rainfall and level for drainage. Position on everything that moves. Measurement for the machinery that keeps the building operating.
Rooftop weather station
The roof is where a building finds out what the weather is actually doing, and it is the only place a met station can go without arguing with the architect.
- MaxiMet GMX551 wind, T, H, P, solar and rainfall in one housing
- MetConnect One Modbus and SDI-12 into the BMS
- WindObserver 75 316 stainless, IP66, for an exposed high roof
Rooftop plant and HVAC
Air handling responds to outside conditions, and a plant deck sheltered by its own parapet is not measuring the same air the intakes are drawing.
- MetConnect THP temperature 0.2 degrees C, humidity 1.5 percent RH
- WindMaster 3-axis for ventilation and air-flow control
- MaxiMet GMX500 wind, temperature, humidity and pressure in one unit
Tall building wind loading
Wind loading and perceived sway are the reasons the structural model exists, and the only way to check the model is to measure the building it produced.
- WindObserver 90 0 to 90 m/s, 316 stainless, no moving parts
- WindMaster Pro 3-axis to 32 Hz for buffeting and vortex work
- WindObserver 75 open head, accurate across a wide flow angle
Facade access and cradles
A building maintenance unit stops at a wind speed, and the crew on the cradle would rather that number came from the facade than the airport.
- WindSonic 60 0 to 60 m/s, 0.5 kg, mounts on the rail or parapet
- WindObserver 75 where the facade position is severely exposed
- Blade position sensors non-contact position feedback on the cradle drive
Tower crane and lifting
An urban lift stops on a wind reading taken at the jib, above a street that will be closed if it goes wrong.
- WindSonic 75 0 to 75 m/s, full-range accuracy published
- WindObserver 90 0 to 90 m/s for tall or exposed jibs
- MaxiMet GMX200 wind only, 0.5 kg, for a temporary works mast
Site hoarding and dust
Dust and noise complaints from a city site arrive with a time on them, and without wind data at the hoarding there is nothing to answer with.
- MaxiMet GMX551 wind, T, H, P, solar and rainfall at the boundary
- MetConnect THP two analogue inputs for dust and noise monitors
- WindSonic 60 a compact wind reference on the hoarding
Pedestrian wind comfort
A tower accelerates wind down its face and around its corners, and the people who feel it are at the bus stop rather than on the roof.
- WindMaster Pro 3-axis to 32 Hz for gust and turbulence at street level
- WindSonic 60 0.5 kg, discreet enough for a street mounting
- MaxiMet GMX200 wind only, for a short pedestrian-comfort survey
Urban heat and outdoor workers
A street of hard surfaces runs hotter than the met office figure, and the people working in it feel radiant heat rather than air temperature.
- MaxiMet GMX552 WBGT heat stress with wind, T, H and P, 1.29 kg, IP66
- MaxiMet GMX300 temperature, humidity and pressure at street level
- MetConnect THP Pt100 input for surface temperature probes
Green roofs and roof irrigation
A green roof is a maintenance liability if it is watered on a timer and a benefit if it is watered on a measurement.
- TruMet PW100 optical rainfall, no bucket to block with substrate
- MaxiMet GMX551 rainfall alongside solar, wind, T, H and P
- MaxiMet GMX301 solar radiation, 0 to 1600 W per square metre
District energy centre
Heat networks and combined heat and power are sized against outside temperature, and they run at their worst efficiency on the day nobody is watching.
- MetConnect THP reference temperature, humidity and pressure
- GS12 Ignition Module up to 12 cylinders, IP67, for CHP engines
- AF120 closed-loop air and fuel ratio control
Smoke control and pressurisation
Stairwell pressurisation and smoke control are commissioned once and then relied on for decades, in the one event where nobody gets to check first.
- MetConnect THP pressure 300 to 1100 hPa, accuracy 0.5 hPa
- Blade position sensors non-contact damper and actuator position feedback
- WindMaster 3-axis air-flow measurement for ventilation control
Barriers, gates and doors
A car park barrier cycles hundreds of times a day, and the sensor proving its position is the part that fails first.
- Blade position sensors non-contact inductive, unlimited-life feedback
- Blade360 contactless rotary position for barrier arms
- Blade Dual Output a second independent channel where redundancy is required
Kerbside air quality
An air quality reading without wind beside it cannot be attributed to the road, the site or the plant, which is exactly what everyone wants to know.
- WindMaster Pro 3-axis to 32 Hz for dispersion at street level
- MetConnect One analogue inputs for third-party analysers
- MaxiMet GMX500 wind, T, H and P alongside the analyser
Drainage, SUDS and attenuation
Sustainable drainage only demonstrates anything if somebody records what the attenuation tank actually did during the storm.
- LevelPro capacitive level, no moving parts to foul
- LevelSlick FEP coated for silty and contaminated water
- TruMet PW100 rainfall intensity to 0 to 200 mm/hr alongside level
Plant room machinery condition
Chillers, pumps and generators fail in a basement nobody visits, and the wear is in the oil before it is in the noise.
- WearDetect oil debris sensing for ferrous wear particles
- LevelPro lubrication and coolant level with no moving parts
- DD1615 level display local indication in the plant room
Ventilation and occupant comfort
Natural ventilation and mixed-mode control open windows on a wind and temperature reading, and get complaints when the reading is from the wrong side of the building.
- WindMaster 3-axis for building and clean-room ventilation control
- MetConnect THP temperature, humidity and pressure into the BMS
- MaxiMet GMX500 one unit, one cable, one output string
Calibration and commissioning evidence
Soft landings, performance in use and a dispute about comfort all come back to whether the instruments were right.
- UKAS-accredited air velocity calibration traceable certification for anemometers
- Multi-parameter calibration six parameters, equipment from any manufacturer
- Recalibration scheduling intervals, reminders and turnaround
The jib decision and the boundary record
At the jib, wind decides whether the lift proceeds, and the number applies to the load rather than to the site. Sail area and configuration change the limit, so the operator needs a live reading rather than a threshold somebody set once.
A compound mast measures a sheltered corner of a site surrounded by the building under construction and by hoardings, which is the wrong answer to a question about conditions at the load.
At the boundary, wind speed and direction turn a dust or noise measurement into an attribution. A concentration reading on its own says something was present; the same reading with wind direction says where it came from.
Both instruments sit in a demolition and construction environment for the duration of a programme, with no maintenance window that anybody wants to take, which rules out anything with a rotating element.
The limit applies to the load
Wind at the jib tip, at the load and at ground level are three different numbers on the same site at the same moment. The one that matters is the one where the load is.
WindSonic measures 0 to 60 or 0 to 75 m/s at 0.5 kg, light enough to mount at the jib without a structural conversation, with no moving parts to seize where nobody can reach it.
Measured where the load is
View WindSonicDirection turns a reading into an attribution
Dust and noise complaints are about a place and a time, and answering them needs more than a concentration. Wind speed and direction recorded alongside the measurement are what establish whether the site was the source.
A compact station at the hoarding provides that alongside the rest of the record. MaxiMet brings wind, temperature, humidity, pressure, solar radiation and rainfall into one unit, and analysers can be integrated into the same station.
Answered with direction, not just a number
View MaxiMetComplaints and claims both arrive late
Dust and noise complaints, delay claims and incident reviews all arrive after the fact and ask about a specific time. A site that recorded conditions continuously can answer; one that did not has to negotiate.
Traceable calibration is what makes those answers hold. For a lift stoppage it supports the delay position, and for a boundary complaint it supports the attribution.
Labcal is an independent UKAS-accredited laboratory operating to ISO/IEC 17025:2017, calibrating equipment from any manufacturer, which suits a site where the crane, the mast and the analysers arrived with different contractors.

Getting both measurements where they are used
The jib reading is acted on in a cab within seconds, and the boundary record is read weeks later by somebody answering a complaint. The same installation has to serve both.
Gill supports environmental monitoring, industrial sensing, embedded electronics and systems integration, so contractors, crane suppliers and monitoring providers can bring measurement into cab displays, site systems and monitoring platforms.
Whether the requirement is an analogue signal into a cab display, Modbus into a site system, a serial string into a monitoring platform, or analyser integration into one station, Gill engineers can support integration from specification through commissioning.
Outputs and options
- Analogue & serial : Cab displays and crane indicators
- Modbus RTU : Site systems and monitoring platforms
- Analyser inputs : Dust and noise instruments into one station
- Traceable calibration : So the record holds up on review
What the specification looks like in practice
Measured where the load is
Jib-tip, load and ground-level wind are three different numbers, and only one of them applies to the lift.
Nothing to seize at the jib
No rotating sensing element to ice, foul or seize in a position reached by climbing the crane.
Light enough to mount properly
WindSonic measures 0 to 75 m/s at 0.5 kg, so it goes where the measurement should be.
Direction makes the attribution
Wind direction alongside a boundary reading is what establishes whether the site was the source.
One installation, two jobs
The lift decision and the complaint record come from the same equipment and the same record.
Defensible when it is reviewed
Independent UKAS-accredited calibration across six parameters, for equipment from any manufacturer.
Questions about urban construction sites
At the jib tip for the reading the lift decision needs, because that is the most exposed point and the closest to the load. A compound mast is sheltered by the building under construction and by the hoardings.
That is set by the crane manufacturer and the lift plan rather than by the instrument. Limits depend on configuration and on the sail area of the load, so the operator needs a live reading rather than a fixed threshold.
Because it turns a dust or noise measurement into an attribution. A concentration on its own says something was present; the same reading with wind direction says where it came from.
Yes. The station can accept third-party and analogue inputs, so dust and noise instruments can be brought into the same record rather than logged separately.
Ultrasonic sensors have no rotating element to foul or seize, and WindUltra is sealed and rated IP66, IP68 and IP69K for mobile plant. There is no service visit required during the programme.
Yes. Labcal is an independent UKAS-accredited calibration laboratory, Lab 0625, operating to ISO/IEC 17025:2017, calibrating equipment from any manufacturer across gas and air flow, air velocity, liquid flow, pressure, temperature and humidity.
