The DK 37 variable area flowmeters can either be equipped with a mechanical or electronic indicator and are suitable for measuring gases and liquids.
They are sturdy, versatile all-metal measuring devices. All devices are fitted with a metering valve to accurately set the flow value.
PPS housing as standard, stainless steel housing as option.
Highlights
Mechanical indicator (M8M)
Without auxiliary power, the flow-dependent position of the float in the measuring cone is transmitted by a magnetic coupling to the scale in the indicator housing. Both adjustable limit values of the transmitters are also displayed on the scale.
Electronic indicator (M8E)
The electronic version with bar graph indicator features state-of-the-art magnetic sensors which record the position of the float without contact or hysteresis. Standard system operation is with a linear analog output in 2-wire technology (applied current 4 to 20 mA). The device can be operated with commercially available power supply units.
Differential pressure regulators
It is possible to directly connect a differential pressure regulator in order to ensure constant flow in the event of fluctuating operating pressure.
