Gauge isolating valves
Purpose-designed hand-wheel operated isolation valves with A.S.V. (auto shut-off valve) to prevent liquid loss if the glass was to be broken.

The CPI tubular gauge is constructed from stainless steel and has P.T.F.E. seals, meaning the gauge is suitable for a wide range of liquids.

Instant dismantling and re-assembly
The CPI gauge tube can be removed from the tank for cleaning or servicing while valves remain sealed and the tank remains leakproof.

Ease of viewing
The level of colourless liquid is indicated by the magnification of a coloured strip on the sight tube.

Where a measure of the precise storage volume is required, graduated gauges can be supplied. The capacity units can either be marked on the guard tube or an engraved scale plate can be provided.

Valve options
Sampling valves and drain/vent valves are available upon request.

Column options
For additional protection and to prevent spillage in the event of a glass breakage, this gauge is available with a double guard tube. This consists of the standard metal guard housed in an additional clear polycarbonate outer guard tube.

Electronic & digital readout
Remote reading systems and/or computer interface options provide a dual system with the advantages of both electronic and sight-glass systems. Level alarms can also be implemented.



Chemical Companions

From volatile solvents to corrosive acids, these indicators withstand harsh chemical environments. Precise level readings for even the most reactive liquids, ensuring safety and process control.
