The data starts with the sensor. For decades, tipping buckets have been the default choice for rainfall measurement. But as networks demand greater accuracy, lower maintenance and more reliable performance, the sensor itself is coming under greater scrutiny. The question is no longer what measures rainfall. It's what measures it best for your network.
Tipping bucket gauges became the industry standard because they were simple, affordable and reliable enough for the data demands of an earlier era. They remain the backbone of many rainfall monitoring networks. Increasingly, however, they are being asked to meet expectations they were never designed to satisfy.
The limitations are well understood. Mechanical gauges can systematically undercatch rainfall, particularly in challenging weather conditions. As data requirements become more demanding and scrutiny around measurement quality increases, the gap between what networks need and what legacy sensing technologies can consistently deliver is becoming harder to ignore.
The industry conversation is beginning to shift. The question is no longer whether solid-state sensing technologies will play a greater role in rainfall monitoring. It is how operators modernise existing networks while balancing performance, cost and operational continuity.
Two very different conversations are shaping the future of precipitation sensing. Treating them as interchangeable is one of the quickest ways to end up with the wrong sensor.
Research stations and national synoptic networks have genuine reasons to invest in advanced optical sensing. These deployments require expanded measurement parameters, higher data granularity and capabilities that go well beyond operational network requirements.
That investment is justified by the science. It also comes with a cost structure and procurement complexity to match.
Most rainfall monitoring networks in operation today are mature. Sites exist, masts are installed, power and telemetry are provisioned, data pipelines are established, audit trails are documented.
These teams are not in the market for an architectural reset. They need a low-friction upgrade that preserves existing infrastructure investment while removing the operational burden of mechanical sensing.
Modernise the sensor, not the network. TruMet PW100 delivers solid-state optical rainfall sensing while preserving the infrastructure, workflows and data pipelines already in place.
Infrared optical sensing eliminates the tipping mechanism entirely. No funnel blockages, no pivot wear, no calibration drift. Reliable from light drizzle to extreme downpours.
Identical pulse output for direct tipping bucket replacement. Existing logging, telemetry and integrations continue to operate as expected. One site visit to commission. No procurement rework.
Emulates tipping bucket pulse output to preserve data pipeline integrity. Long-term climate records and regulatory reporting continue without recalibration.
Accumulation measurement at high reliability. No drop size distribution, no reflectivity factor Z. The capital difference funds the next ten monitoring points.
Tell us about your existing infrastructure and we will recommend the right path forward.
Not every network needs every capability. Many operational rainfall networks simply require reliable accumulation measurement. Paying for functionality that never influences an operational decision comes at a cost.
The capital invested in over-specified sensors is capital that cannot be invested in greater coverage. Often, a broader network with more monitoring points will deliver more useful operational insight than a smaller network built around capabilities that remain unused.
Density is an economic question as much as a scientific one. The strongest networks match sensing technology to the application, infrastructure and operational realities of the organisation. Not because it creates a better specification sheet, but because it delivers better data where it matters.

Common questions from network operators and system integrators. If yours isn't covered, ask our team directly.
Yes. The PW100 provides an identical pulse output for direct tipping bucket replacement. The tip size is set to 0.1mm, so if your existing gauge uses a different tip size, a small datalogger adjustment is required to align.
No configuration is required before use or after installation. There is no setup needed from the factory. No field calibration is required, and test data to date has not identified any calibration drift requiring ongoing attention.
Requirements vary by environment. Sites with high dust, sand, pollen or coastal airborne debris may need more frequent lens cleaning. The unit internally compensates for gradual lens contamination by increasing LED power to maintain constant receiver intensity. Periodic cleaning is recommended as a precaution.
Yes. The PW100 is rated to operate at -35°C and can remain installed year-round. It is designed for liquid precipitation only and there is no heater to remove snow buildup, so data will not be collected during frozen precipitation events.
The PW100 and GMX603 have a stated accuracy of ±5% and are designed as quantitative tipping bucket replacements. The optical sensor on the GMX240, GMX400 and GMX600 has no accuracy specification and is intended only for applications requiring a rain present / rain absent indication.
Yes. The TruMet includes a direction marker to eliminate the risk of the receiver being flooded by direct sunlight. In the northern hemisphere, point the direction marker east. In the southern hemisphere, point it west.
The PW100 provides pulse output only, designed as a direct tipping bucket replacement. For users needing digital communications including SDI-12, the MaxiMet GMX603 integrates the same optical precipitation sensing alongside full weather station output and supports all GMX600 communication protocols.
