Measure Flow with Confidence Using Differential Pressure (DP) Transmitters

Highly Accurate and Reliable Flow Measurement

About DP Flow Measurement

Differential Pressure (DP) Flow Measurement is one of the most common and trusted technologies for measuring flow within a closed pipe. DP Flow Measurement is based on the principle of Bernoulli’s equation, which relates the pressure drop across a restriction (such as an orifice plate, venturi tube, or flow nozzle) to the flow rate of the fluid.

The OleumTech Differential Pressure Transmitter serves an invaluable role in industrial settings, offering superb accuracy and reliability in measuring pressure differentials, which is vital for maintaining and controlling optimal flow rates. Its advanced design ensures precise readings even in harsh environments, providing crucial data for optimizing operations and ensuring safety. With its high precision and reliability, the OleumTech DP Transmitter is widely deployed in oil and gas, chemical processing, and water treatment applications, enabling informed decision-making and ensuring the smooth operation of complex systems.
