Core component advantage

Digital Flow Sensor

PRODUCT ADVANTAGE

flow switch is mainly in the water, gas, oil and other media pipeline online or plug-in installation to trigger the switch output alarm signal when the flow is higher or lower than a certain value, the system can make the corresponding execution unit action SOR flow switch is based on the flow to command the system switch.

The upper limit or lower limit is set for the flow switch. When the flow reaches the limit value, the flow switch will send a signal or alarm, and the system will run or stop. Generally, systems that require flow will use flow switches.
Can set and detect flow rate
Can display instantaneous flow or cumulative flow
There are two types of sensors and displays: integrated and separate
2 outputs, can independently set different flow rates
There are switch outputs, cumulative pulse outputs, and analog outputs
