Product details
These easy to use, intrinsically safe rate totalisers can process and simultaneously display rate of flow and total flow from the pulse output of most flowmeters. International certification allows worldwide installation and a 16 segment lineariser ensures maximum accuracy.

Accessories, include a display backlight, isolated dual alarms, isolated 4/20mA output for BA337E and BA337E-SS and isolated synchronous pulse output.

Rate totalisers can be supplied configured and fitted with a customer specified printed scale card showing the units of measurement for no additional charge. Specified tag or application information can also be printed onto the rear of the instrument.

Other externally powered rate totalisers in our range include:
