How to Install a Turbine Flow Meter
Turbine flow meters are engineered with internal components that are water-resistant, providing a long service life and trouble-free operation. Fluid flowing in the device is initially conditioned or calibrated by the inlet flow straightener, reducing turmoil in the liquid.
The flowing fluid makes the rotor blade to spin and rotate at a rate that’s equivalent to its flow rate. As the rotor blades pass through the electromagnetic field, an electronic pulse or voltage is generated.
This electronic pulse can be utilized to see the total amount of fluid that has traversed through the measuring device or the actual flow rate of fluids. The number of generated electronic pulses by the flow meter is called the K-Factor.
If you’re wondering how to install a turbine flow meter, here’s how. Read on!
Before installing the flow meter device, it must be examined and inspected for any foreign material. Also, to make sure the rotor blades spin and rotates correctly. All upstream liquid lines must be free of any dirt and debris.
Moreover, ensure that the fluid flow has been, for the most part, turned off. Additionally, make sure that all pressure in the upstream fluid lines has been discharged before installing the device into an existing operating system.
The turbine flow meters should be mounted with the flow direction pointing in the fluid flow’s path. You can find the flow direction arrow on the side of the measuring device.
The flow indicator is engineered to function in any position. However, the ideal position is to have the flow meter mounted in horizontal piping.
The liquid to be calculated or assessed must be filtered. The ideal location for the strainer or filter would be in the upper part of the flow meter device, after any system parts. And at the same time keeping the straight piping requirements in mind.
The ideal plumbing orientation is one holding a bypass line. In this way, it allows flow meter repair and inspection without impeding the flow. Additionally, it can cycle the fluid flowing through the filter before it goes through the flow meter.
However, if a bypass line isn’t utilized, then all of the flow control valves must be situated in the lower part of the flow meter. For maximum turbine flow meter performance and efficiency, a minimum length of downstream and upstream piping is needed.
It’s ideal to have a minimum length of at least ten diameters of straight pipe be mounted straightforwardly on the upper part of the flow measuring device. On the other hand, at least five diameters on the lower part of the measuring tool.
It aids in eliminating turmoil in the fluid. If the meter has shorter vessel lengths, some system components might negatively influence the repeatability and accuracy of the flow meter. For this reason, piping must be the same size as the port size or meter bore.
Don’t locate the connection cable or flow meter near the electric motes, high voltage lines, sparking devices, or transformers. Also, don’t put connecting cable in a pipe with wire giving power for such tools.
Such devices can cause false or incorrect signals in the measuring device. Thus, causing the turbine meter to give inaccurate readings.
Running The Device For The First Time
The following methods must be perceived when installing the turbine flow meter and operating it after installation.
- Open the bypass valve and secure the isolation valves after installing the flow meter. The fluid flow throughout the system needs ample time to get rid of any gas or air in the flow line.
- Gradually open the upper isolating valve to let the liquid to flow in the device.
- Then, open the lower isolating valve to trigger the fluid to flow through the meter, allowing it to operate.
- Secure or lock the bypass valve entirely.
- If the lower valve is utilized as a flow control valve, then fine-tune or modify the valve to get the desired flow rate through the turbine flow meter.
Take note that gas and air, flowing at an extreme velocity, can wreck the internal parts of the turbine flow meter. Also, never pound or smash the flow meter. This action can damage internal parts permanently.
Turbine flow meters are volume measuring device. As gas or liquid traverse through the device, it causes the rotor blades to spin and rotate.
The turbine rotor’s velocity is equivalent to the velocity of the fluid flowing through the meter. There are a lot of turbine meters to select from relying upon your application.
When you understand the application, a couple of factors materializes when picking a flow meter, for example:
- Specific application
- Accuracy range
- Flow range
- Pressure range
- Process temperature
- Pipe sizing
- Fluid type
If you want flow rate measurement or total volumetric flow, then a turbine meter is the best option.
