Henke DW-U Analog Pointer Flowmeter with 2 Switches


The Henke DW-U flow meter is simple, reliable, adjustable with analogue display. You can monitor the switching status with its switching point and LED. The metal tube flow meter DW-U works by moving the flow pedal towards the flow direction depending on the flow. This is a reliable way. The function fluid flow causes a pendulum system with a target plate to move on a shaft against a spring. Thanks to its metal bellows design, it isolates the measuring device from the flow environment and enables the conversion of the pendulum movement. The movement of the pendulum activates a 3-pole microswitch, which sends a signal to the flow control system, which in turn activates the flow indicator.
