This third generation, intrinsically safe BA358E 4/20mA loop powered Rate Totalizer 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 linearization or square root extraction are selectable and the instrument can display and totalize bi-directional flows.
No additional charge is made for factory calibration or for scale card and tag marking, however the Rate Totalizer 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.
We are an authorized BEKA distributor shipping to locations in the United States.
