Flow switch installation is crucial for accurate flow gauging. There are a few tips you should follow. Also, there’s a lot you should avoid. However, if you do everything right at the installation stage, you will have a smooth time gauging and reading your flow measurements. Below are the dos and don’ts for industrial flow meters.
- Install the pressure gauge near the meter inlet. It helps to tap all the pressure at the inlet. That is the correct pressure of water as tr gits into the flow system. You will be able to detect the pressure drop throughout the flow channel. Also, you will be able to estimate the point where the pressure will stabilize. Thus, you can know where to install your flow switch.
- Place the throttling valve at the meter’s outlet. It helps to tap the pressure of the fluid as it exits the meter. Also, it will get the best signals to detect the fluid flow rate.
- Ensure you have pipe sealers on the connections—that way. You are sure there is no leakage in the channel. You’ll be able to reduce losses and prevent pressure drip. You’ll also protect your flow system from damage.
- Have proper calibration of your meter. Each flow switch will function well if it is calibrated to the fluid it is gauging. Each fluid has varied traits depending on many factors. Every time you want to change the fluid, you should calibrate your flow switch. Some meters are sensitive to fluid characteristics like temperature and pressure. If you are using such a meter, ensure you have controlled your fluid traits. If you need to change them, then you should calibrate the meter.
- You should have scheduled maintenance of your flowmeters. Some meters are exposed to silting and sedimentation. The solids affect the flow of fluid and the accuracy of the meter. Thus, you will need to remove them after a certain period. Other aspects need to be checked during maintenance. For instance, you need to prevent any leaks. It would help if you also calibrated the meter to ensure you are getting the correct readings.
- Mount your meter according to the instructions. In most cases, you should install the meter vertically. It ensures there’s no pressure drop and the meter readings are accurate. However, there are some meters that you should install horizontally. If you erect them vertically, you will get the wrong readings.
- Use the solenoid valves at the meter outlet. It helps to direct the flow in the right direction.
- Ensure you install a union in one direction. The union helps in the easy removal of the meter. It comes in handy when you need to calibrate or replace the meter.
- If your fluids are in extreme heat and pressures, invest in a meter that can handle it. Any meter that does not accommodate extreme temperatures and pressures will break down when exposed to extremes.
- Do not install the meter where there’s a likelihood of flow reversal. Flow reversal leads to wrong meter readings. Also, it prevents the smooth functions of a meter and can accelerate the rate of damage. However, it’s possible to use a flow switch near a reverse flow if you have an RF option on the meter type.
- Do not place the meter on non-aligned piping. Such piping creates a lot of disturbance. Thus, it alters the fluid traits. It’s possible to have the wrong readings due to changed fluid characteristics.
- Each meter has a pressure and pressure range. Never operate the flow switch with fluids with higher or lower heat and pressure ranges. It accelerates the speed of meter deterioration. Also, you will get the wrong readings. This mistake is costly and may make you buy a new meter after a short time.
- Never install a solenoid valve at the inlet. Although it controls the flow, it will interfere with the pressure and fluid flow velocity getting into the meters. In the end, you will get erratic readings.
- Do not install restrictions between the pressure gauge and the inlet of the meter. It disrupts the fluid pressure and changes the fluid velocity. It makes you get the readings that do not reflect the overall fluid rate.
A flow switch is vital in fluid flow. It helps control the flow of fluids throughout the change. Also, the flow meters will help you calculate your profits and evade losses. Ensure you follow the tips above to maximize your meter use.
