Strainer Monitoring

Used to monitor pressure drops across strainers in petroleum/ chemical industry.

Differential pressure instruments are used to monitor pressure drop across strainers used in line with positive displacement flow meters. Petroleum oil companies and chemical plants use positive displacement flow meters to measure volume. Contaminated fluids can damage these expensive and critical flow meters. Strainers are used to filter the process to keep the flow meters functioning properly.  Positive displacement flow meter manufacturers specify the maximum pressure drop across the meter and  strainer. The engineer / buyer uses this information to purchase components for the system  As pressure drops increase across the strainer to due captured particulates, energy costs increase.   Piston type and diaphragm type differential pressure instruments are ideal for this application.
