1) Pressure range. The range should be selected so that the anticipated working pressure is approximately half of the range of the gauge. This ensures that the gauge will be working in the most accurate part of the range. Do not use gauges constantly above 75% of it's maximum. Reduce this figure if the pressure is cyclic.

2) Never pressurise a gauge above it's maximum. Install relief valves if necessary to prevent this.

3) Ensure that the liquid entering the gauge is compatible with the gauge materials. Chemical gauges with diaphragm seal should be used for corrosive liquids. Hazardous area gauges should be selected by a competent instrumentation engineer.

4) The maximum temperature rating of the gauge should not be exceeded. If temperature exceeds 65 degrees C use siphons or a different type of gauge construction. Contact us for details.

5) Please refer to the manufacturers instructions for the use of gauges with steam, oxygene, acetylene etc.
