8041 Electromagnetic Flow Transmitter

Brand: Burkert Fluid Control Systems

The electromagnetic flow transmitter 8041 has been designed for pipes with diameters ranging from 1/4" to 16" and liquids having a conductivity > 20 µS/cm. 

The transmitter is a magmeter made up of an electronic module and a sensor which armature is in PVDF or stainless steel. It is fitted with a 4-20 mA output, a pulse rate output and a relay output. 

The different parameters can be programmed by means of 5 switches, a push-button and a 10 led bargraph. The version with a stainless steel sensor can be used in applications with higher pressures (232 psi) and higher temperatures 150° C (302° F).
