It is important to be able to determine contents of tank at any given time, and to be able to actuate pumps, alarms etc. A variety of contents gauges and switches are available, differing in method of operation, source of power, accuracy and price. Gauges and switches illustrated are amongst the most popular cost efficient and time proven systems produced.
We would however be please to recommend the best instrument to suit your particular application and to supply additional data to help you make your selection.
Prices listed apply to gauges and switches supplied with Integ tanks or vessels. Add cost of fixing flange or socket, valving etc. as required.
