These easy to use, Ex nA and Ex tc certified rate totaliser can process and simultaneously display rate of flow and total flow from the pulse output of most flowmeters in Zone 2 or 22 without the need for Zener barriers or galvanic isolators. International certification allows worldwide installation and a 16 segment lineariser ensures maximum accuracy.

The two input model can display the sum or difference of the two inputs.

Accessories, include a display backlight, isolated dual alarms and an isolated 4/20mA output. The instrument can be supplied configured and fitted with a customer specified printed scale card showing the units of measurement for no additional charge. An optional stainless steel legend plate is also available which can be supplied laser engraved with customer specified tag and application information.
