A battery powered rate totaliser with separate rate and total displays. This device will count switch contact closures, voltage pulses and the low level output from magnetic pick-offs.

Main application of the BA544D is to process the pulse output from a 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. When fitted with optional alarms, the BA344D will perform simple flow batching applications, and an optional pulse output allows a remote counter to be operated.

The BA344D may also be used for speed monitoring of turbines and other rotating machinery.

Control and programming of the BA544D is performed via four push buttons, which are protected from damage and tampering behind a sealed cover. For applications requiring frequent adjustment, the instrument can be supplied with a robust external membrane keypad. All the programme functions are contained in easy to understand menus, that can be protected by a user definable security code. Battery Life is typically five years but depends upon the application. The BA544D includes a sophisticated power control system which progressively reduces current consumption when input pulses and control commands are not being received. The display includes a low battery warning annunciator, which will be activated a few months before the battery is exhausted. If the battery is not replaced, the displayed total and all programme parameters will be automatically stored in the permanent internal memory before the BA544D stops functioning.
