5 Things to keep in mind when installing a flow meter

 

      Install the flow meter yourself





Following the purchase of a flow meter, proper installation and calibration are the subsequent stages in maintaining the equipment over its lifetime and lowering the cost of ownership to maximize the total facility’s cost savings.

Once you’ve decided on the ideal flow meter for each fluid and application, making sure that it is installed correctly, is crucial for accurate flow readings. If your flow meter “doesn’t function,” it’s likely that it wasn’t installed correctly.

Let’s have a look at some typical installation suggestions to help you save money and get the most out of your flow meters.

1- Check the measuring fluid conditions-


Make sure the fluid you’re measuring is a single-phase fluid, which means it’s either a gas or a liquid. If the fluid is two-phased, the flow meter must be selected with the expectation of measurement under such conditions in mind. Also check the conductivity of the fluid, because some flow meters work well only in a certain range of conductivity. The fluid type is important and needs to be checked, as in cases like steam flow measurement, the steam user has to be clear about whether the steam is saturated or super-heated. In the case of hydrocarbons, only certain types of flow meters work. The same thing is true for the measurement of gas flow, where only specific types of flow meters like Thermal Mass Flow Meters work.

2- Check Flow Meter orientation-

The orientation of a flow meter’s installation can have a significant impact on the meter’s performance and accuracy. A straight run of at least 10 diameters upstream and 5 diameters downstream is required in most installations. Figure-1 shows ideal locations for flow meter installation.


3- Check if the flow pipeline is fully filled-

Even if there is no flow, the flow meter should always be put in a position where it is filled with fluid when installing a flow meter. Figure-2 shows suggested pipeline modification if a partial flow condition exists.



4- Installing pipeline to avoid bubbles-

Gas escapes the liquid solution due to a sudden pressure drop in the flow line. Valves with sudden variations in diameter are prone to gasification. This can create problems in flow measurement. Therefore, it’s critical to build the pipe in such a way that bubbles don’t form. Piping design experts need to be consulted when there is a complex piping network.

5- Flowmeter calibration-

When it comes to determining efficiency, performance, and cost savings, your flow meter’s measurement accuracy is crucial. As a result, the more precise your flow-meter is, the more reliable data you’ll have, to make cost-cutting decisions. So, before you install the flow meter, make sure it’s calibrated for accuracy. It is advisable to get all the flow meters on the field calibrated periodically.

You can ensure optimum functionality of your flow meter now that you’ve learned about the most critical guidelines for installing a flow meter.

Making Mass Flow Meters in India – for the world!

Image
  Direct mass flow measurement of gases T he story of Development of Thermal Dispersion Mass Flow Meter by Manas. The Thermal Dispersion Mass Flow Meter is a comparatively new concept. In India, nobody was manufacturing it with indigenous technology. Even today, it is mostly imported in India from the US or some other European countries. The cheaper versions are also available from China. It is consuming a lot of foreign exchange of the country. Right from the beginning, Manas has worked on the strategy of developing and manufacturing the technology products in India. This was the main reason for going after the development of the Thermal Mass Flow Meter. The most important issue was how to test the meters under development or even a developed meter. A flow calibration laboratory was essential for this reason. The Thermal meter being a mass Flow Meter, the laboratory also required the capability of calibrating in terms of mass measurement. So, the first challenge was, setting up a ca

  What is water flow meter? And how does water flow meter work? The amount of water flowing through a pipe is measured using a water flow meter . Depending on the application for water being measured, the required level of maintenance, and the available budget, there are various water flow meter technologies to pick from. Each of these water flow meter types have a different operating principle, offer advantages for a particular application, and have an overall cost of ownership. So, which water flow meter is best for your application involving water flow measurement? Ultrasonic flow meters, magnetic flow meters, mechanical water flow meters and vortex volumetric flow meters are some of the important types of water flow meters. Ultrasonic Flowmeter for Water Industry Ultrasonic water flow meters use ultrasound to gauge a fluid velocity as it travels through a pipe in order to calculate volumetric flow. An ultrasonic signal is transmitted in the direction of the flowing fluid downstrea
