Flow switch ST-7, 4 lpm, 2x3/8" internal thread
ST-7 is an advanced and reliable flow meter for professional high-pressure installations.
The model is installation position independent, which provides great flexibility during installation, and it is developed for demanding operation with high pressure and large flow rates.
This version is completely redesigned and is based on a completely new operating principle.
Instead of the traditional and highly sensitive reed switches, a robust industrial microswitch with high switching capacity is used.
This makes it possible to connect significantly larger electrical loads and at the same time achieve a longer service life.
The electrical and hydraulic components are completely separated, which increases operational reliability and enables the components to be assembled efficiently in series production.
Despite the high maximum flow rate, very precise switching points can be achieved.
The pressure drop in the flow meter is also low, only about 1.5 bar at 30 l/min.
