Monitoring differential pressure (∆p) is critical in a wide variety of production processes. Measuring differential pressure is essential wherever small differences in pressure can have a significant effect, such as monitoring pressure drop across filters, strainers, separators, valves and pumps, displaying liquid levels in tanks, leak detection, and measuring liquid flow. Applications include clean rooms, laboratory & test equipment, heat exchangers, refineries, petrochemical plants, hydraulics & pneumatics, power generation, water management and chemical plants.
Piston type differential pressure gauges are designed primarily for liquid or gaseous media applications where low differential pressure ranges and static working pressures are needed. Diaphragm type differential pressure gauges isolate the high and low-pressure ports from each other, so there is no bypass. These gauges can be used in applications measuring air, gas or liquids.
