The BA338C is an external powered rate totaliser with separate rate and total displays which will operate from a switch contact, pulse, magnetic pick-off or a proximity detector input. Main application of the BA338C is to process the pulse output from a hazardous area flowmeter, and to display the rate of flow and the total flow in the same or different engineering units. The instrument may be used with any flowmeter having a pulse output proportional to flow rate, such as a turbine flow meter. For maximum accuracy the BA338C may be supplied with a 16 point lineariser to compensate for flowmeter non-linearity. When fitted with optional alarms, the instrument can perform simple flow batching applications, and an optional pulse output allows a remote counter to be operated.

Rotational speed of machinery may also be measured and displayed by the BA338C. The instrument will operate from most intrinsically safe 2-wire proximity detectors and, when fitted with alarms, over and under speed warnings can be generated. 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.
