Product details
This third generation, intrinsically safe BA354E 4/20mA loop powered Rate Totaliser has large high contrast rate and total displays with an extended operating temperature range. It can display flow rate per second, minute or hour and total flow in the same or different units. Adjustable linearisation or square root extraction are selectable and the instrument can display and totalise bi-directional flows.

No additional charge is made for factory calibration or for escutcheon scale and tag marking, however the Rate Totaliser can easily be recalibrated on-site.

Coated printed circuit boards plus extensive thermal and vibration testing provides maximum reliability supported by a three year guarantee.

To select the options for your application please refer to the following table.
