Why are Paddle Wheel Flow Meters Suitable for DI Water?
Paddle wheel flow meters are a type of flow meter that are commonly used to measure the flow of liquids, such as water, in pipes. They are particularly suitable for measuring the flow of deionized water because deionized water is a clean, low-viscosity fluid that does not contain any ions or other contaminants that could interfere with the operation of the flow meter.
The basic principle behind paddle wheel flow meters is relatively simple. They consist of a paddle wheel that is mounted in a pipe through which the fluid being measured is flowing. As the fluid flows past the paddle wheel, it causes the paddle wheel to rotate. The rotation of the paddle wheel is then used to calculate the flow rate of the fluid.
There are several different types of paddle wheel flow meters, including mechanical, magnetic, and ultrasonic. Mechanical paddle wheel flow meters use the rotation of the paddle wheel to directly measure the flow rate of the fluid.
They can be either direct reading or rate indicating, depending on whether they display the flow rate directly or need to be calibrated to a specific fluid. Magnetic paddle wheel flow meters, on the other hand, use a magnetic field to measure the rotation of the paddle wheel, which is then used to calculate the flow rate of the fluid. Ultrasonic paddle wheel flow meters use sound waves to measure the flow rate of the fluid and are generally more accurate than mechanical or magnetic paddle wheel flow meters.
Paddle wheel flow meters are suitable for use with a wide range of fluids, including water, oil, and other liquids. They are particularly well-suited for use with clean, low-viscosity fluids such as deionized water, as these fluids are unlikely to cause any problems with the operation of the flow meter.
Paddle wheel flow meters are also relatively easy to install and maintain, making them a popular choice for many applications.
One of the main advantages of paddle wheel flow meters is their accuracy. The Truflo® TK and TI series paddle wheel flow meters are generally able to measure flow rates with an accuracy of +/- 0.5% or better, depending on the type of flow meter and the specific application. This makes them a reliable choice for applications where accurate flow measurement is important.
Overall, paddle wheel flow meters are a suitable choice for measuring the flow of deionized water because they are able to accurately measure the flow rate of clean, low-viscosity fluids, and are relatively easy to install and maintain. They are also suitable for use in a wide range of applications, making them a versatile choice for many different types of projects.
