Accurate and Reliable Flow Meter for Ultrapure Liquids

A majority of liquid flow meters are developed for industrial applications such as oil & gas, food & beverage, but ultrapure liquids require a high rate of accuracy. The flow meter must be capable of measuring flow ranges of microliters and even Nano liters per minute.

Ultrapure liquid flow meters are the ideal solution for measuring fluids that must remain uncontaminated and pure. Used predominantly in the pharmaceutical and power industries, ultrapure liquid flow meters ensure accurate analyses and maintain safety. This type of flow meter ensures that the ultrapure liquid remains free from contamination during the measurement process.

Listed below are examples of flow meters used to measure ultrapure liquids:

Pelton Wheel

The radial turbine or Pelton wheel is the best choice for monitoring and measuring low-viscosity fluids such as water. Using small sensing coils, it detects ferrites, which are located within the application’s rotor blade tips. These blade tips turn according to the speed proportion of the ultrapure liquid’s flow rate. Since the Pelton Wheel has large blades, it is suitable for measuring low flow rates. The ferrites are enclosed, preventing them from coming into contact with the ultrapure liquid. The Pelton Wheel flow meter has sapphire bearings. It provides a low-friction and non-metallic solution for measuring ultrapure liquids such as water.

Vortex Shedding

The vortex shedding flow meter is an example of an oscillatory flow meter. It operates by detecting incited vortices that are generated within the fluid. During the detection of these vortices, the velocity and flow rate are measured.

The Vortex Shedding flow meter is ideal for measuring flow rates of ultrapure liquids because it utilizes the fluid’s properties, i.e. density, pressure, and viscosity, to prompt fluctuations in order to make calculations. Therefore there is no risk present of contaminating the ultrapure liquid.

Volumetric Shedding flow meters are ideal for measuring volumetric flow rates and low viscosity liquids such as water and similar condensates.

Ultrasonic

Ultrasonic flow meters rely on ultrasonic waves to gauge the frequency shifts and traveling times of flow. The waves travel through the liquid flow and accurately calculate required parameters. This is why they are well suited for measuring water and liquids. Clamped-on and inline flow meters are two types of ultrasonic flow meters. They differ in how they are installed.

Turbine

Turbine flow meters have vanned rotor. As fluid traverses it, it measures the average velocity of the fluid. The vanned rotor is located within the flow meter. It is centered on a shaft where it rotates on its bearings. Tube bundles support the shaft. They provide an element of flow conditioning, which adds to the accuracy of a flow reading.

Turbine flow meters are an excellent choice for measuring ultrapure liquids because of their high precision and wide size range. They also have the ability to maintain the purity of water.
