Perfect for meteorological stations, environmental monitoring, and water resource management.

2. Rainfall Transmitter 
This rain measurement instrument offers an assortment of beneficial features, ideal for environmental research and wastewater, irrigation, and stormwater monitoring and controls. These include:

• Exceeds EPA and NWS specifications
• Built-in bubble level
• Removable housing for easy maintenance
• 8-inch 304 stainless steel body and orifice tunnel
• Ceramic magnet
• 12-24VDC powered translator board that converts pulse output from the tipping bucket to a 4-20mA signal.

3. Precipitation Transmitter
This rain measurement instrument is fully electronic with no moving parts. It provides accurate precipitation sensing including rainfall, snow, sleet and hail measurement without concern for clogging. Several features include:

• 24 Ghz Radar sensing
• Faster response time than mechanical sensors
• More precise measurement than mechanical sensors
• No moving parts
• Ma7
• 12-24VDC with either RS485 or SDI–12 Output

How Rainfall Measuring Instruments Work

Rainfall measuring devices operate by collecting and quantifying precipitation over a set period:

• Tipping Bucket Gauges: Use a small seesaw mechanism that tips each time a specific amount of rain is collected, sending a pulse signal for data logging.
• Electronic Radar Sensors: Use advanced radar pulses to detect raindrops and measure precipitation in real time without physical collection.
• Optical Rain Sensors: Detect rainfall by measuring light scattering patterns from falling droplets.

Applications of Rain Measurement Instruments

Our rainfall measuring devices are used worldwide for:

• Agriculture: Optimizing irrigation schedules, conserving water, and protecting crops.
• Environmental Monitoring: Tracking climate patterns, rainfall distribution, and drought risk.
• Construction & Civil Engineering: Managing stormwater runoff and preventing flooding.
• Water Treatment Plants: Monitoring inflow during rain events.
• Hydrology & Flood Studies: Collecting accurate rainfall data for watershed and flood modeling.

Choosing the Right Rainfall Measuring Device

When selecting a rain measurement instrument, consider:

• Accuracy requirements – High-precision for research vs. standard for general monitoring.
• Measurement type – Rain only, or rain plus snow and hail.
• Data output – Pulse, 4–20mA, RS485, or SDI–12.
• Durability – Materials resistant to corrosion and environmental wear.
• Maintenance – Ease of cleaning and calibration.
