Flow Rate Switch

A flow rate switch is a sensor device that commands the system based on flow rate, primarily used to monitor the size of water flow in a water system and trigger an output alarm signal when the flow rate exceeds or falls below a set point, to avoid or reduce the main unit from “burning dry”.

The working principle of the flow rate switch is based on monitoring the size of water flow in the installed water monitoring system. When the water flow reaches or exceeds the set flow rate, the switch will send a signal or alarm. The system then performs the corresponding action, such as starting or stopping, to ensure the normal and safe operation of the system. This type of switch is widely used in pipelines of water, gas, oil, and other media, and can be installed online or inserted.

In terms of technical features, the flow rate switch boasts multiple advantages:

Dual-regulating technologyEasier adjustments and more accurate display.

Dual Relay OutputEase control.

LED lightReflects the current size of the traffic.

Ultra-small housingIntegrated design, made entirely of stainless steel, practical and aesthetically pleasing.

Working VoltageSupports DC24V, AC/DC110V, AC/DC220V, with operating current less than 60mA.

Operating TemperatureWide range, covering from normal temperature to high temperature models.

Response TimeFast, with a typical value of 2 seconds.

Electrical ProtectionIncluding reverse polarity, short circuit, and overload protection features.

In addition, flow rate switches come in various types, including fixed pressure difference flow switches and piston flow switches, catering to different application needs. The fixed pressure difference flow switches are specifically designed for OEM clients, offering single set-point pressure difference switches to ensure rational and accurate flow control. On the other hand, piston flow switches are widely used in industries such as industrial automation, machinery equipment, air compressor, refrigeration and air conditioning, thanks to their pressure loss, good repeatability, and anti-fouling capabilities.
