We aim to respond within 1 hour

Priced from £2200
Accuracy from ±0.6% (reading) or ±0.2% (full scale), whichever is greater
Typical indication response time from <100 ms (T98)

KCO series of Coriolis flow controllers from Alicat Scientific with a standard accuracy calibration are available in four main body sizes with typical full scale flow rates of 40, 1000, 10 000 or 100 000 grams per hour (g/h).

Accuracy for liquids with a standard accuracy calibration is NIST traceable to ±0.6% of reading or ±0.2% of full scale (whichever is greater). When used with gases the NIST-traceable calibration is to ±1% of reading or ±0.2% of full scale again whichever is greater. Repeatability is offered at ±0.1% of full scale with steady state control range available from 5% - 100% of the full scale range.

A typical control response time is less than 1,000 ms (T98), with typical indication response times of less than 100 ms (T98) for 40 g/h to 10,000 g/h controllers. This increases to less than 200 ms (T98) for 30,000 g/h to 100,000 g/h controllers.

All Coda Coriolis flow meters and controllers have been designed to be inherently resistant to external vibrations, eliminating difficult environmental and process conditions.
