Comptus precipitation measurement instruments, sensors and transmitters are used in many industrial applications including flood, stormwater, wastewater, irrigation, snow and rain detection.
Our technologies include precipitation measuring devices such as tipping bucket gauges, radar, and surface moisture detection, including leaf wetness. Options for analog and digital signal transmission ensure compatibility with all common data logging and control systems. Sensitivity levels are available from .01” down to .1mm.
Our weather instruments, precipitation gauges, rain gauges, and transmitters meet US Weather Service specifications and are factory calibrated to ensure accuracy. Consult the sales team at Comptus should other calibration setups be desired.

Our precipitation measurement instruments are engineered to perform in harsh conditions, from extreme cold to heavy rainfall. Built from stainless steel, aluminum, and UV-resistant materials, they deliver long-term reliability.
Comptus devices integrate seamlessly with control systems using analog, digital, pulse, 4-20 mA, RS-485, or SDI-12 outputs.
Most of our precipitation measuring devices are calibrated to US Weather Service (USWS) standards, providing readings as low as 0.01″ (~0.25 mm).
Yes. Electronic and radar-based precipitation measuring devices can accurately detect rain, snow, sleet, and hail without clogging or mechanical issues.
Installation depends on the model. Tipping-bucket and radar-based gauges should be installed on a level surface or post, away from obstructions, with proper grounding and sensor calibration as per the manual.
Data can be collected via pulse outputs, analog (4-20 mA), digital, RS-485, or SDI-12 signals and integrated into weather stations, SCADA systems, or data loggers
Calibration frequency depends on usage and environment, but typically once per year for tipping-bucket gauges and every 2–3 years for electronic gauges.
Tipping-bucket gauges may need periodic cleaning of the funnel and bucket. Electronic and radar gauges require minimal maintenance—mainly checking sensor alignment and clearing debris.
Yes. Many Comptus gauges support remote data logging and telemetry, making them suitable for weather stations, research sites, or agricultural fields.
Most devices support inches, millimeters, or custom increments. Tipping-bucket gauges can have resolutions as low as 0.01″ (0.25 mm).
Properly installed Comptus gauges account for wind, temperature, and debris. Electronic and radar-based devices minimize errors caused by environmental factors compared to mechanical gauges.
Yes. Precipitation gauges with digital or analog outputs can trigger irrigation systems, HVAC controls, or smart building alerts based on precipitation levels.
Yes. Most gauges provide standard outputs like 4-20 mA, RS-485, SDI-12, and pulse signals, making integration with existing systems easy.
Comptus instruments combine rugged industrial design, high precision, versatile outputs, compliance with NWS/EPA standards, and a wide range of models for any application.
