What should I consider when choosing a weather station?

Selecting the right weather station depends on the parameters you need to measure, the environment, communication protocols and how the data will be used. Factors such as long-term reliability, maintenance requirements, environmental protection and system integration are often as important as measurement accuracy. Gill weather stations are designed for professional applications where dependable environmental data supports operational decisions.

Five questions, in this order

• Which parameters, and which are genuinely required? Every parameter added is cost, weight and one more thing to verify. Solar radiation and rainfall are the two most often specified and least often used.
• One unit or separated sensors? This is the fork that decides the product line, and it is a siting question rather than a preference.
• What does the site do to it? Icing, salt, wind speed and access.
• What has to receive the data? Protocol, not just output type.
• Who maintains it, and how often can they get there?

Integrated or separable

MaxiMet puts everything in one housing: one unit, one cable, one output string. It is faster to install, cheaper to cable and has fewer things to align.

MetConnect separates the sensors so they can sit at different heights, which is what WMO-compliant siting requires, and it accepts third-party inputs so an existing sensor does not have to be discarded.

Then pick the model

The two traps

Heating is not all the same. MaxiMet heating is transducer-only and low power, around 7 W. It is not full sensor heating. On a site with severe icing that is not enough, and the answer is a heated WindObserver or WindSonic M for the wind element. Say what the heating is rather than implying more.

Integrated wind is 0 to 60 m/s. Every Gill weather station uses WindSonic ultrasonic technology for wind. If the site needs a higher range or a formal marine or aviation wind approval, that is a WindObserver job. On a cold site, MetConnect One’s integrated wind sensor is unheated, so the answer is MetConnect THP plus a heated anemometer.

Integration, before you order

• Confirm the protocol the receiving system speaks, not just the electrical interface. MetConnect offers RS232, RS422 and RS485 with ASCII, Modbus RTU and ASCII, NMEA 0183 and SDI-12 v1.3.
• Check the power budget at the far end of the cable run, not at the supply. MetConnect draws under 70 mA at 12 V DC before heating.
• Decide the output period. MetConnect gives one measurement per 1, 2 or 4 seconds, or polled.
• Agree who owns the configuration file. MetSet and MetView are free, and a station configured once and documented is a station that can be replaced identically in three years.
