Third generation loop powered 4/20mA Rate Totalisers that have larger digits and improved display visibility, plus ATEX, IECEx, FM and cFM certification for the intrinsically safe models.
All are mechanically, electrically and safety compatible with the earlier instruments, so that existing system designs do not have to be re-engineered to benefit from the performance and economic advantages of these new 'E' instruments.
All the new models, which can simultaneously display the rate of flow and total flow in the same or different engineering units, have an extended operating temperature and include a square root extractor, sixteen segment lineariser and internal calibrator. Optional accessories include a backlight that may be loop or separately powered and dual alarms with isolated solid state outputs.
