Type 8041 – Electromagnetic insertion flowmeter
The electromagnetic flowmeter Type 8041 consists of an electronic module and a sensor made from PVDF or stainless steel. It is suitable for pipelines with a nominal diameter of between DN 06 and DN 400 and neutral or aggressive liquids with conductivity greater than 20 μS/cm. Type 8041 is fitted with a 4 mA to 20 mA current output, a frequency output and a relay output. The device is configured using 5 DIP switches, a push button, and a 10-segment LED bar graph. This flowmeter is available with either a G2” connection for a PVDF sensor or a G2” or clamp connection for a stainless steel sensor, both of which are designed for use with a Type S020 insertion fitting. The variant with stainless steel sensor is for applications with higher pressures (PN 16) and higher temperatures (150°C).
