When you use the flow transmitter, something about the fluid property you should know.
The fluid contains gases, liquids, vapors, etc., and different fluid properties can cause different flow phenomena. Therefore, when using the flow transmitter, please note the fluid properties, see the tips listed below:
1. Density: Reference fluid name, and calculate density based on temperature, and pressure.
2. Viscosity: Viscosity can be conceptualized as quantifying the frictional force that arises between adjacent layers of fluid that are in relative motion. For instance, when a fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. In such a case, experiments show that some stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow through the tube. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion: the strength of this force is proportional to the viscosity.
3.Conductivity: When you use the electromagnetic flowmeter for fluid measured, must be a conductive liquid.
Because it is an instrument for measuring the flow rate of a conductive fluid based on the electromotive force induced by an externally applied magnetic field using an electromagnetic induction principle.
4.Contaminants: Such as bubbles in the fluid, mud, foreign matter mixed in, etc.
5.Flow range: For confirm the minimum and maximum flow of fluid.
6.Fluid temperature: For confirm fluid temperature, make sure the working range that can be used.
7.Fluid pressure: For Confirm fluid pressure to select the appropriate working pressure for the flow transmitter.
8.Pressure loss: Confirm the pressure loss of the flow transmitter when measuring the fluid.
Pressure loss is energy loss, not only the downstream pressure will decrease, but also the flow rate and flow rate will decrease.
According to the above conditions, it will help you choose the best flow meter, there are too many principles of flow measurement, check with a professional sale who you trust also is an option.
