Simple, very reliable flow meter with analog display of the current flow, adjustable switching point, optical switching display via glow lamp.
Proven measuring method
The DW-U from HSW functions according to the reliable way deflection system. The pendulum system with the pressure plate (deflector) is moved by the flowing medium against the strength of a spring. A metal bellow seals the system from the medium to the measuring and display part. The movement transmission is done by force. A micro-switch arranged in the measuring part and a control lamp are activated. Corresponding switching processes are triggered by this micro-switch. Furthermore, a display system is activated that shows the current flow quantity on the scale.
