Tipping Bucket Rain Gauge, Dry-Contact Pulse Output, 304SS, Max 10mm/Min, 4% Accuracy

1. Introductions

TBRG400 is Tipping Bucket Rain Gauge Sensor, an instrument for testing rainfall in the nature. In order to meet the requirement of information transmission, processing, recording and display, the amount of rainfall is converted to pulse output. It can be widely used in weather stations, hydrometric stations, agriculture & forestry, defense & field monitoring stations. It can provide the original data for flood-prevention, water-supply system, and reservoir water management in plant.

3. Working Process

Rainfall is captured in the 200mm diameter collector funnel and is directed through a delivery pipe to fill a divided ABS injection molded tipping bucket device.The bucket is pivoted through its center and has a preset calibration to tip for 0.2 mm of rainfall. When the bucket is “full”, it pivots and empties - this action magnetically closes and opens a reed switch, sending a pulse signal to the data logger or electronic counter. Through this tipping “seesaw” action, the other side of the bucket is aligned to receive the flow from the delivery pipe. This recording and tipping cycle continues with rainfall.

Step 3: Fix the sensor pins and adjust the height of the pins so that the bubble inside the sensor is centered.

(If the bubble is centered, it means the sensor is balanced)
