SPI-73 Flow Meter

Brand: SIMEX sp. z o.o.
The SPI-73 flow counters are designed to work together with flow transducers equipped with contact or electronic inputs.

The purpose of flow counters is to measure the instantaneous flow value and to record the total flow of media like liquids, gases or loose materials.

A wide range of total flow indication: up to 16 digits allows controlling the flow value for a long operation time.

The REL / OC control output can be programmed depending on the instantaneous flow value, batcher or total flow value.

The counter can be configured with the local keyboard or free S-Config software via the RS-485 communication port.
