Description

A thin, spring-mounted shutter that covers the entire flow cross-section is displaced by the flow of the liquid. The shutter has a magnet that creates a changing magnetic field when the shutter is displaced. This field is detected by an analogue hall-sensor. Due to the spring properties of the shutter and a molded stop, even strong media impacts can be withstood. The low number of parts coming into contact with mediaguarantees low soiling properties and reliable operation.

Since the shutter functions only through bending without a rotary bearing, there are no friction effects and thus a very small hysteresis and good reproducibility of the measurement results or switching point. The low mass and evaluation of the entire flow crosssection are responsible for the fast response time and unproblematic pipeline routing.

Full metal type

The basic type is manufactured with a plastic body and is withstanding a pressure of 16 bar. A full metal body (brass, nickel-plated) withstanding 100 bar is available as an option. The use of metal fittings and connection hardware is mandatory due to the increased higher pressure strength. Measurements or switching value adjustments can be done in the range of 1…80 litres/min.

High temperature

If the full metal type is equipped with high-temperature sensors, a media temperature of up to 150˚C can be performed and monitored. The primary sensor element is then placed in the measuring unit, while the evaluation unit is located at the end of a 0,5 m heat resistant cable.
