Strainer Monitoring

Flow Meters for Water Monitor Pressure Drops Across Strainers in the Petroleum/Chemical Industry

Differential pressure flow meters for water play a crucial role in monitoring the pressure drop across strainers, which are commonly integrated with positive displacement flow meters. Within industries such as petroleum and chemical plants, these meters serve the purpose of accurately measuring volume. However, the susceptibility of these valuable flow meters to damage from contaminated fluids necessitates the use of strainers, which effectively filter the process and maintain the meters’ optimal functionality.

To ensure the seamless operation of the system, manufacturers of positive displacement flow meters specify the maximum pressure drop that can be sustained across both the meter and the strainer. This vital information serves as a guiding factor for engineers and buyers in the procurement of suitable system components. As the pressure drop intensifies due to the accumulation of particulates within the strainer, the energy costs associated with the process also increase.

For applications of this nature, piston type and diaphragm type differential pressure instruments are deemed particularly well-suited, owing to their ability to facilitate an effective and efficient flow monitoring process.
