Product list
DFYT Integrated Orifice Flowmeter
The DFYT Integrated Orifice Flowmeter incorporates an orifice plate, a three-valve manifold, a differential pressure transmitter, and temperature/pressure compensation into a single unit. Each unit is pressure-tested as a complete assembly prior to delivery, with actual flow calibration available as an option. The straight pipe section is precision bored and honed, ensuring high accuracy and excellent coaxiality. The design allows for straightforward installation and maintenance, with an accuracy of up to Class 0.5.
DF Multi-Hole Orifice Flow Meter
The multi-hole balanced orifice is the 3rd-generation throttling device. Measurement accuracy is 5~10x better than traditional orifice plates, with permanent pressure loss of only ~1/3. Multi-hole symmetric design balances and conditions the flow field.
DF Standard Nozzle Flowmeter
The standard nozzle features a rounded-profile design that offers low pressure loss, short straight-pipe run requirements, and high accuracy. It is particularly suited to flow measurement of high-temperature, high-pressure steam and high-velocity fluids in power plants, and complies with ISO 5167-3:2022. The unit is integrally forged without welded seams, ensuring safe and reliable operation.
DF Standard Venturi Flowmeter
The Venturi tube produces a permanent pressure loss of only about one-eighth of the differential pressure value, offering significantly lower pressure loss and substantially shorter straight-pipe run requirements compared to other standard throttling devices. It is widely used for flow measurement of fluids such as air, natural gas, coal gas, water, and steam, and complies with ISO 5167-4:2022.
