Flow technology turbine flow meter China, this article takes you to understand everything before purchasing turbine flow meters.

Turbine flow meter is often used for liquid and gas measurement. The gas turbine is mainly natural gas. Liquid Turbine Flow is the turbine flow meter suitable for liquid flow rate measurement. Like water flow, Diesel flow. The turbine flow meter is the most popular equipment to measure flow electronically. They offer a wide flow and application rangeability. Turbine Flow Meters are easy to maintain, durable and versatile.

Turbine flow meter Advantages and Disadvantages
Turbine Meter Advantages
- The cost is moderate.
- Very good at clean, low viscosity fluids of moderate velocity and a steady rate.
- Turndown is very good as it can read very low compared to the greatest flow.
- They are reliable if put in a clean fluid especially if it has some lubricity.
- AGA and API approved for custody transfers.
- They do cause some pressure drop where that may be a factor such as gravity flows.
- High accuracy. Among all flowmeters, it is the most accurate flowmeter.
- No zero drift, good anti-interference ability.
- High accuracy. Among all flowmeters, it is the most accurate flowmeter.
- No zero drift, good anti-interference ability.
Turbine Meter Disadvantages
- Not reliable for steam.
- Bearings wear out.
- Requires constant backpressure to prevent cavitation.
- Accuracy adversely affected by bubbles in liquids.
- Turbine meters can be used with clean liquids and gases only (may need to install a strainer upstream to prevent damage from particulates).
- Not applicable for measuring corrosive fluids.
- May not function properly with high viscosity fluids where the flow profile is laminar.
- Cannot maintain calibration characteristics for a long time.
What is a turbine flow meter?
Turbine flowmeter is to install a rotor in the circulation channel, when the liquid flows through it will drive the blades to rotate. Then the flow rate is measured according to the number of rotations.
The intelligent liquid turbine flowmeter is a new type of intelligent instrument that integrates the turbine flow sensor and display integration, which is developed using advanced ultra-low power single-chip microcomputer technology. It has the obvious advantages of compact structure, intuitive and clear reading, high reliability, no interference from external power supply, lightning resistance, and low cost.
How to calibrate a turbine flow meter?
Use the volumetric tank method to calibrate the turbine flowmeter.
The volume of the standard water tank is determined by filling the standard water tank with water, which is measured by a water tank calibrated and certified by the National Institute of Standards and Technology.
Regularly check the volume of these calibration tanks. Each flow meter and kit are placed in the assembly line, and the calibration tank is filled at five different flow rates within the range of the meter. One round is executed at the maximum rate, one round is executed at the minimum rate, and the three rounds are executed at an equidistant interval between the maximum rate and the minimum rate.
Record the total number of pulses generated by the flowmeter at each flow rate. Divide the total pulse by the total volume at each flow rate to determine the calibration factor. The average factor is determined to be half between the high factor and the low factor.
The flowmeter is marked with an averaging factor. For industrial grade instruments, the maximum deviation between the average coefficient and the upper or lower limit coefficient cannot exceed ±0.5%, and for standard grade instruments, it cannot exceed ±1.0%.
The above is the whole content of how to calibrate the turbine flowmeter. If you have any questions or purchase requirements, please contact Sino-Inst directly.
How does a Coriolis meter measure flow?

The principle of Coriolis mass flowmeter mass measurement is Newton’s second law F=Ma. When the fluid flows in the vibrating tube, it will produce Coriolis force proportional to the mass flow.
When there is no fluid flowing, the vibrating tube will not be twisted, and the signals detected by the electromagnetic signal detectors on both sides of the vibrating tube are in phase.
When fluid passes by, the vibrating tube will be twisted under the action of torque, and there will be a phase difference between the two detectors.
The transmitter measures the lag time between the left and right detection signals. This time difference is multiplied by the flow calibration coefficient to determine the mass flow.
The density measurement principle of Coriolis mass flowmeter is that the vibration frequency is inversely proportional to the square root of the fluid density. The fluid density is determined by measuring the vibration frequency.
Therefore, the mass flow meter can realize the measurement of fluid mass flow and the measurement of fluid density.
