The BA358C is a loop-powered field mounting rate totaliser with separate rate and total displays. When connected in series with a 4/20mA flow transmitter, the BA358C will display the rate of flow in engineering units and total flow in the same or different units. The BA358C only introduces a 1V drop which allows it to be installed in almost any 4/20mA loop. Main application of the BA358C is to integrate the 4/20mA output from a flow transmitter and to display the total flow in engineering units. The flow rate is shown on a smaller display, although the function of the two displays may be reversed.

A selectable root extractor enables the output from a differential flow transmitter to be displayed in linear units. When fitted with optional alarms, the BA358C can detect low or high flows and can perform simple flow batching applications. Control and programming is performed via the front panel tactile push-buttons which 'click' when operated. All the programme functions are contained in easy to understand menus which may be protected by a user definable security code. Display scaling factors employ floating decimal points to simplify calibration.
