More about Turbine Flow Meters

What is a turbine flow meter?

A turbine flow meter is a volume sensing device. As liquid or gas passes through the turbine housing, it causes the freely suspended turbine blades to rotate. The velocity of the turbine rotor is directly proportional to the velocity of the fluid passing through the flow meter.

The external pickoff mounted on the body of the flow meter, senses each rotor blade passing, causing the sensor to generate a frequency output. The frequency is directly proportional to the volume of the liquid or gas.

What is the principle of turbine flow meter?

Gas turbine flow meter working principle

The gas turbine flowmeter uses a turbine for measurement. It first converts the flow rate into the rotational speed of the turbine, and then converts the rotational speed into an electrical signal proportional to the flow rate.

Gas turbine flowmeter is used to detect instantaneous flow and total integrated flow. Its output signal is frequency, which is easy to digitize.

The induction coil and the permanent magnet are fixed on the housing together. When the ferromagnetic turbine blade passes the magnet, the reluctance of the magnetic circuit changes, thereby generating an induction signal.

The signal is amplified and reshaped by the amplifier and sent to the counter or frequency meter. The total accumulated flow is displayed. At the same time, the pulse frequency undergoes frequency-voltage conversion to indicate instantaneous flow.

The speed of the impeller is proportional to the flow, and the number of revolutions of the impeller is proportional to the total amount of flow. The output of the turbine flowmeter is a frequency modulated signal. It not only improves the anti-interference of the detection circuit, but also simplifies the flow detection system.

The gas turbine flowmeter has a turndown ratio of up to 10:1, and the accuracy is within ±0.2%. The time constant of the turbine flowmeter with small inertia and small size can reach 0.01 second.

Liquid Turbine Flow Meter Working Principle

Liquid Turbine Flow Meter is a speed type flow meter based on the principle of torque balance.

The fluid flows through the sensor housing. Because the blades of the impeller have a certain angle with the flow direction. The impulse of the fluid makes the blades have a rotational torque. After the friction torque and fluid resistance are overcome, the blades rotate. The speed is stable after the torque is balanced.

Under certain conditions, the speed is proportional to the flow rate.

Due to the magnetic permeability of the blade, it is in the magnetic field of the signal detector (composed of permanent magnets and coils). The rotating blade cuts the magnetic lines of force. The magnetic flux of the coil is periodically changed. Electrical pulse signals are induced at both ends of the coil.

This signal is amplified and reshaped by an amplifier. A continuous rectangular pulse wave with a certain amplitude is formed. It can be transmitted to the display instrument remotely. The instantaneous flow or total amount of the fluid is displayed.

Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor. The flow equation is:

f——Pulse frequency [Hz]
k——The meter coefficient of the sensor [1/m3], which is given by the calibration sheet.
Q——The instantaneous flow of fluid (under working condition) [m3/h]
3600-conversion factor in seconds

The meter coefficient of each sensor is filled in the verification certificate by the manufacturer. The k value is set in the matching display instrument. The instantaneous flow and cumulative total can be displayed.

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.

Types of turbine flow meter

Generally speaking, according to the measuring medium, we can divide the turbine flowmeter into liquid turbine flowmeter and gas flowmeter.

Of course, according to the function of the turbine flowmeter, we can divide the turbine flowmeter into a basic turbine flowmeter and an intelligent turbine flowmeter.

  1. Basic turbine flowmeter

The turbine sensor itself does not have the on-site display function, and only transmits the flow signal remotely.
The flow signal can be divided into pulse signal or current signal.
Low price, high integration, small size, especially suitable for use with secondary display, PLC, DCS and other computer control systems.

  1. Intelligent turbine flowmeter

Intelligent turbine flowmeter, a display integrated instrument developed by combining turbine flow sensor and advanced ultra-low power single-chip microcomputer technology.
It has the advantages of compact structure, high reliability, resistance to external power supply interference, lightning protection, and low cost.
Three-point correction of instrument coefficients can be carried out on site, and nonlinearity of instrument coefficients can be intelligently compensated.
Simultaneously display instantaneous flow, cumulative flow, temperature, pressure and other measurement parameters.
It has real-time data storage function and explosion-proof function.
Especially suitable for use with PLC, DCS and other computer control systems.

What is k factor in turbine flow meter?

K-factor (K value) is a factor calculated by calibrating and comparing the meter with other measuring devices that meet the accuracy requirements before putting it into use.
This coefficient is a fixed value, which is the actual coefficient obtained by the flowmeter manufacturer for each meter after verification, and has nothing to do with the initial design.

There are two kinds of different manufacturers k:
One is k=f/Q, which is the number of vortices generated by du unit flow;
The other k=Q/f, that is, each vortex corresponds to the flow rate of Zhuan.
The k value is calibrated with factory water. The sensor measures the vortex number of the instrument and compares it with the volume flow measured by the calibration device to obtain the k value.

The k value is actually related to the internal mechanical structure of the flow meter measuring tube.
