8025 Transmitter Flowmeter
Brand: Burkert Fluid Control Systems
The remote 8025 Universal transmitter can be associated with Burkert flowmeter 8020, 8030, SE30 + S077 or another flow sensor which emits a frequency signal (with pulse output signal). The remote 8025 transmitter can only be associated with Burkert flowmeter 8020, 8030, SE30 + S077 with sinus or pulse output signal in a “Low Power” version.
When connected to a flowmeter, the device makes it possible to switch a solenoid valve, activate an alarm or generate a flow rate proportional frequency, thanks to a digital output and, for some versions, by means of two relay outputs, fully configurable, and to establish a control loop thanks to a 4-20 mA current output.
