Obsolete Turbidity Instruments
We have supplied a turbidity instrument before our current range of controllers. They were used to make up systems for customers as alarms to divert out of specification liquid to either storage tank or for retreatments back through the site waste water plant.
The model ATW1 is designed to provide simple, reliable, accurate and dependable measurement and control of the Turbidity of an industrial effluent discharge. The ATW instrument is fitted with one control relay and a non isolated current output for chart recording or data logging.
To keep the installation simple and measurement cost effective only two sensors were manufactured, a dip sensor for installation in open vessels, and a flow line sensor built into a 2’’ PVC tee with a quick release fitting for easy removal of the sensor
Replacement instrument Model TU7685 Turbidity controller with two control relays, alarm relay and an isolated 0-20 / 4-20 mA output.
