Differential Pressure Flow Series

The Elbow Flow Meter utilizes the fluid inertia principle to generate differential pressure at the elbow for flow measurement. It has no insertion/throttling elements, no additional pressure loss, and is suitable for harsh environments such as high temperature, high pressure, dust, and vibration. It is widely used in thermal power, electric power, and metallurgy industries.

Nozzle flow meter is a standard differential pressure generating device. Used with a differential pressure transmitter, it measures flow of liquids, steam, and gases. It features lower pressure loss than orifice plates, is robust and durable, suitable for high-temperature and high-pressure fluids, and is widely used in power and chemical industries for steam metering.

The Balanced Flow Meter utilizes a multi-hole balanced rectification design, offering flow performance close to that of a Venturi tube. Its accuracy is 5 to 10 times higher than traditional throttling devices, requires short straight pipe runs (0.5D to 2D), reduces permanent pressure loss by approximately 70%, and has a wide turndown ratio, making it suitable for custody transfer metering.

Wedge flow meter is a new type of throttling differential pressure flow meter, suitable for high-precision measurement of high viscosity, low Reynolds number (≥500), large diameter and small flow conditions, with self-cleaning ability, no stagnation zone, wear resistance, and lower pressure loss than orifice plate.

Annubar (averaging pitot tube) flow meter is based on the pitot tube velocity measurement principle, outputs differential pressure signal, can measure flow of liquid, gas, and steam in circular/rectangular pipes, easy installation, extremely low pressure loss, high strength, ideal replacement for orifice plates.

V-Cone flow meter is a new type of differential pressure flow meter. It suspends a cone-shaped throttling element in the center of the pipe to reshape the velocity profile, offering a wide rangeability (10:1), low straight pipe requirements (upstream 0~3D), and resistance to contamination and wear. It can measure water, steam, natural gas, and various other media.

The standard orifice plate flowmeter is the most widely used differential pressure throttling device. Paired with a differential pressure transmitter, it measures flow of liquids, gases, and steam. It is highly standardized, can be put into use without real-flow calibration, and features a simple, robust, and reliable structure.
