What is the principle of clamp type turbine flowmeter

Clamp type turbine flowmeterIt is a precision flow measurement instrument that can be used to measure the flow rate and total amount of liquids when paired with corresponding flow integrator instruments. Equipped with sanitary connectorsClamp type turbine flowmeterSensors can be applied in the pharmaceutical industry, displaying total flow rate, instantaneous flow rate, and flow rate percentage. The instrument has three-point correction for instrument coefficient, intelligent compensation for instrument coefficient nonlinearity, and can be adjusted on-site. Turbine flowmeter is a practical instrument for measuring liquid flow rate. It has high accuracy, good stability, and is easy to use, so it is widely used in various industries for flow measurement. There should be no 5xD straight pipe section in front of the flowmeter and no 3xD straight pipe section in the back. To facilitate installation and disassembly, a pipeline expansion joint can be installed behind the flowmeter.

The uneven distribution of flow velocity and the presence of secondary flow inside the pipe are important factors affecting the measurement accuracy of turbine flowmeters, which have certain requirements for the upstream and downstream straight pipe sections. To eliminate secondary flow, it is good to install a rectifier at the upstream end. If the upstream end can ensure a straight pipe section of about 20D and install a rectifier, it can makeClamp type turbine flowmeterThe measurement accuracy reaches the accuracy level at the time of calibration. There is a high requirement for the cleanliness of the fluid, and a filter must be installed before the flowmeter to ensure the cleanliness of the fluid. The filter can be funnel-shaped, and its cleanliness can be measured by measuring the differential pressure change at both ends. To ensure that the liquid passing through the flowmeter is single-phase, that is, air or vapor cannot enter the flowmeter, a deaerator should be installed upstream of the flowmeter if necessary. For liquids that are prone to gasification, a certain back pressure must be ensured downstream of the flow meter. The magnitude of this back pressure can be twice the pressure drop of the flow sensor at high flow rates and 1.2 times the vapor pressure of the measured liquid at high temperatures.
