Product details
This 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.
Accessories, include a display backlight, isolated dual alarms or isolated synchronous pulse output or 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. Specified tag or application information can also be printed onto the rear of the instrument.
Other externally powered rate totalisers in our range include:
- Intrinsically safe field mounting
- Intrinsically safe panel mounting
- Type nA field mounting
- General purpose field mounting
- General purpose panel mounting
