The MV145 part of the FLOWIZ family is a battery-powered converter for flow meters that can power any ISOMAG sensorinsertion or flanged up to DN1800. The MV145 is also able to manage up to two pressure or temperature sensors.

The MV145 can be powered by lithium or alkaline batteries  and can be easily replaced, without interrupting the measurement.
Batteries have an estimated life of 15 years or more based on measurement conditions.

Optionally the MV145, can be powered from the mains, c.a. or c.c. or from a solar panel via the DC connection; in this case the batteries have a backup function, avoiding data loss in the event of a power failure.

The MV145 coupled to the MS2500 flow sensor (up to DN1000) complies with the European directive 2014/32/EU MID, Annex III MI-001.

The converter has an internal logger capable of storing flow and pressure data with a recording capacity of 4 GByte, which guarantees years of recording.
The instrument is equipped with complete diagnostics thanks to the BIV (built-in verifier) which constantly monitors various sensor parameters, anticipating possible problems.

Allows programming via keyboard and display or with mini USB cable connected to the PC via MCP software.

The battery converter for flow meters MV145, flow metersenergy metersultrasonic flowmeters, and industrial automation systems have been ISOIL Industria‘s passion and continuous research since 1958, and for any information or advice please do not hesitate to contact our specialists.
