Rate Totalisers
 |
Features:
• Separate easy to read rate and total flow displays • Robust enclosures, including Stainless Steel panel mounting instrument • Isolated synchronous pulse output option on small panel models • Models: • One pulse input, externally powered Two pulse inputs, externally powered 4/20mA input, loop powered Field and panel mounting • Certifications: • Intrinsically safe Ex ia Ex nA & Ex tc for Zone 2 & 22 applications General purpose for use in safe area • Accessories: • Backlight Isolated dual alarms Isolated 4/20mA output Pipe mounting kits Scale and tagging • Three year guarantee This extensive range of rate totalisers includes models for use with pulse and 4/20mA output flowmeters. The rate of flow and total flow are displayed simultaneously in the same or in different engineering units. All parameters are easy to adjust on-site allowing these rate totalisers to be used with almost any flowmeter. Instruments can be supplied ready to install with customer specified configuration, scale and tag marking. For more information, please choose the model which best suits your application from the tables below. |
These UK designed and manufactured instruments include fourth generation models which have even larger displays, more digits and international certification complying with the latest standards for the hazardous area models. The range now includes increased safety Ex eb and Ex tb models which are a lower cost alternative for flameproof indicators, but have much larger easy to see displays.
Indicators can be supplied ready to install with customer specified calibration, scale and tag marking for no additional charge.
