Thanks for your quick responce.  This Insertion type mag flow meter really works well in our wastewater pipes.

Techincal Support

A turbine flow meter is a volume sensing device, constructed with rotor and blades. Turbine flow meters use the mechanical energy of the fluid to rotate the rotor in the flow stream. 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 proportional to the velocity of the fluid.
 
Rotor movement is often detected magnetically, where movement of the rotor generates a pulse. When the fluid moves faster, more pulses are generated. Turbine flow meter sensors detecting the pulse. Located external to the flowing stream. To avoid material of construction constraints that would result if wetted sensors were usedThe RPM of the turbine wheel is proportional to flow velocity within the tube diameter and corresponds to the volume flow over a wide range.
 
A flow transmitter mounted on the body of the flow meter. Transmitter processes the pulse signal to determine the flow of the fluid. Flow transmitter and sensing systems are available to sense flow in both the forward and reverse flow directions. High accuracy are available for custody transfer of hydrocarbons and natural gas.

There are two different manufacturers k:
one is k = f / Q, which is the number of vortices generated per unit flow;
the other is k = Q / f, which is the flow corresponding to each vortex.
The k value is calibrated by the factory water.
The number of vortices of the sensor measuring instrument is compared with the volume flow measured by the calibration device to obtain the k value.


The value of k is actually related to the mechanical structure inside the measuring tube of the flow meter.
Take k = f / Q as an example, the formula is as follows:

How do you calculate K factor for a turbine flow meter?
Where

D —- Measuring tube diameter

St —- Strauhal number, constant in a certain range of Reynolds number

d —- characteristic width of vortex generator

m–the ratio of the arcuate area on both sides of the vortex generator to the cross-sectional area inside the pipe


The values of d and m are difficult to measure accurately, so it is difficult to obtain accurate k values by calculation.

Turbine Flow Meters

Turbine type flow meter

Turbine type flow meter is one type of mechanical flow meters. Turbine flow meter use the mechanical energy of the liquid to rotate a rotor in the flow stream. Turbine flow meters measure the velocity of a variety of liquids (oil, water), gases (natural gas) and vapors. All types turbine flow meters, like: flange, sanitary flow meter, insertion, threaded connections etc .

sanitary flow meter

Sanitary Flow Meter

Sanitary Flow Meter, also called the tri-clamp flow meter. Sanitary Flow Meters have stainless steel bodies and come standard with Tri-Clover fittings. Sanitary flow meter meets the requirements of the food, and beverage company industries. Sino-Inst’s magnetic flowmeter and turbine flow meters is available in a sanitary version. And allows for use with Output Modules, Sensors and Remote Transmitters.

Wastewater flow meter

Wastewater flow meter

Wastewater Flow meters are flowmeters for water and wastewater treatment. Electromagnetic flow meters are suitable for open channel and underground industrial water pipes. Magnetic flow meters can be Remote type, compact type, insertion type. And ultrasonic flow meters are another choice, if you can not change your pipes. Both ultrasonic flow meters and magmeters are inline flow meters. Sino-Inst offers ultrasonic and magnetic flow meters, which offer the highest flow meter accuracy and reliability, as well as long-term stability and a low cost-of-ownership.

Water Flow Meter Types

Water Flow Meter Types

Water Flow Meters are flow meters measure and show the flow rate of water flow. Water flow measurement is important for inductrial applications, like the wastewater treatment. In principle, water flow meter types are: Electromagnetic (magnetic), Turbine, Ultrasonic, and DP. Coriolis and Oval Gear flow meters can also work for water flow measurement. These water flow meters, optional with digital display, battery, analog or pulse output. Material can be 316 stainless steel or special material.
