High pressure turbine flow meter is one of the most popular types of high pressure flow meters due to its high accuracy and repeatability. It is also relatively easy to install and maintain. High pressure turbine flow meters work by measuring the rotation of a turbine blade that is caused by the flow of fluid passing through the meter. It is the best choice for flow measurement of various high-pressure liquids and oils.

The housing is made of stainless steel. The meter has a simple structure and optimized structural design. High-pressure butt-weld flange clamping or high-pressure threaded connection structure is used.

  • High pressure structure design, up to 40MPa.
  • Advanced micro-power high-tech, low power consumption.
  • new sensors, low initial flow and low pressure loss.
  • High accuracy with good overlap
  • multiple output modes for easy system integration.

Main applications.
Chemical high-pressure pipeline, hydraulic oil, circulating oil, oil stations, construction machinery and other high-pressure occasion liquid.

The main disadvantage of high pressure turbine flow meters is that they are not suitable for applications where the fluid contains solids or particles, as these can damage the meter.

High pressure orifice plate flowmeter

A high pressure orifice plate flowmeter is a device used to measure the flow of fluids through a pipe. It consists of a plate with an opening in the middle, through which the fluid flows. The plate is placed in the path of the fluid stream and the pressure drop across the plate is measured. This pressure drop is then used to calculate the flow rate. High pressure orifice plates are used in applications where the fluid being measured is under high pressure, such as in steam, oil and gas pipelines.

  • Applicable measured media is very wide, can be used for almost all gases, steam and liquid flow measurement.
  • Use pressure up to 32MPa, also can be used for negative pressure.
  • Medium temperature range: -30°C to +650°C.

Bar type flowmeter will be inserted into the center of the pipe probe, the total pressure hole on the direction of the incoming fluid flow. Static pressure hole to the direction of the fluid to flow. The difference between the total pressure and static pressure is the measured differential pressure in the center of the pipe. Then the standard differential pressure at that point is fitted by the wind tunnel calibration curve of the probe.

It is mainly used in high temperature and high pressure high flow rate or ultra-high temperature and ultra-high pressure steam flow meter. It is made of high temperature resistant and impulse corrosion resistant 1Cr18Ni9Ti material.

The complete metal chamber structure is adopted to ensure the strength and steel. So that no damage to the mechanism will occur under the washout of high-speed airflow.

Matching temperature and pressure sensors are used to compensate for the temperature and pressure of the measured medium to ensure measurement accuracy.

  • High temperature and pressure resistance: the primary element intelligent probe material selection 1Cr18Ni9Ti stainless steel ( according to different media selection of special steel ).
  • Can withstand the maximum temperature of 650 ℃, the highest medium pressure 32MPa.

high pressure coriolis mass flow meter

Mass flow meters are based on the Coriolis principle. The flow tube through which the medium flows vibrates, thus triggering the Coriolis effect. The sensor detects and analyzes the change in frequency, phase difference and amplitude of the flow tube. The mass flow rate and density of the fluid are calculated.

The high pressure coriolis mass flow meter is pressure resistant to 24 MPa. The type of process connection as well as the ambient and process medium temperature may reduce this rating.
