Waterflow Detector

The sensitivity of the waterflow detector should be within the range of 4 to 10 gallons per minute, with a maximum static pressure rating of up to 232psi. It is suitable for pipes ranging from 2 inches to 8 inches (50 mm to 200 mm). It can respond to the water flow in the specified direction after a preset delay, and this delay function can also be adjusted on site.

waterflow detector with retard can filter out interference signals such as short-term waterflow fluctuations and water pressure impacts in pipelines, preventing false alarms in the system. It is widely used in hotels, shopping malls, restaurants, entertainment venues, hospitals, office buildings, factories, warehouses and other places where water is used for fire fighting in medium and light hazard buildings.

How to install a water flow indicator switch? 

The pipeline connected to the water flow indicator switch must ensure that the length of the straight pipes before and after it is not less than five times the diameter of the pipeline. When selecting the water flow indicator switch, the corresponding selection should be made according to the nominal diameter of the pipeline in accordance with the technical parameter table.

When installing, pay attention to the direction of water flow, which should be consistent with the arrow on the product. The delay parameters have been preset at the factory. If adjustment is needed, it must be operated by professional fire protection technicians. Non-professionals are strictly prohibited from disassembling the delay module.

Wiring must strictly match the rated voltage of DC24V. It is strictly forbidden to connect the wrong polarity or use it under overvoltage to avoid damaging the delay circuit.

Note: After the installation of the water flow detection sensor, it should be inspected once every six months, with a focus on checking whether the water flow response, delay function and contact output are normal. Keep the electronic components of the product dry and clean to prevent water vapor and dust from entering.
