MST200-Standard Panel Mounted Flow Controller

The purpose of flow controller working with flow sensor is to measure the flow rate 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 rate for a long operation time. Thanks to the built-in batcher function the MST200 can be used in many industries like: food pharmaceutical or paint and varnish industry. The REL/0C control outputs can be programmed depending on the flow rate, total flow or batcher. Additionally the controller may be equipped with analogue outputs, according to the customer selection: active current output ( 0/4 ...20mA ) , passive isolated current output ( 4 ... 20mA ) or active voltage output ( 0/1 ..5V,0/2...10V ) . The controller can be configured with the local keyboard or free S-Config software via the RS-485 communication port.
