As specialists in the design, manufacturing and supplying of flow measuring applications, Litre Meter provides top of the range flow meters suitable for all jobs, as well as a wide selection of materials.
Different materials – whether gas or liquid – have different characteristics. Their given pressures will differ, as well as their temperature, density, conductivity, and composition for example. This is why we offer a variety of flow meters, because some are better suited to certain fluids than others.
Below, you can find the ideal flow meters for measuring ultrapure water. Predominantly used in power and pharmaceutical industries, ultrapure water needs to stay pure and deionised for both safety purposes and accuracy of analysis.
These flow meters ensure that the fluid is not contaminated during the measuring process, maintaining its ultrapure state.
The Pelton Wheel, also known as a radial turbine, is the ideal choice for measuring and monitoring low-viscosity liquids like water.
It uses a small sensing coil to detect the ferrites found in the application’s rotor blade tips as they turn at a speed in proportion to the flow rate. The Pelton Wheel’s large blades make it suitable for measuring very low flows. The ferrites are sealed in ensuring they do not come into contact with the liquid.
With its sapphire bearings, this flow meter provides a non-metallic and low-friction solution to measuring the fluid, making it ideal for ultrapure water.
All oscillatory flow meters, like Vortex Shedding, work by detecting provoked vortices that are made from the fluid to determine its flow rate and velocity.
As it uses the fluid’s own properties (its pressure, density, and viscosity for example) to induce the fluctuations to make its calculations, it runs no risk of contaminating ultrapure water of other particles or gases.
It’s well known as one of the best choices to measure volumetric flow rate and low viscosity liquids like water and other condensates.
Ultrasonic flow meters use ultrasonic waves to measure the travelling times and the frequency shifts of a flow.
The waves pass through the flow to accurately calculate the information, and work particularly well for measuring water and other liquids.
There are two types of ultrasonic flow meters, clamped-on and inline, which differ in the way that they are installed.
Using a vaned rotor, a Turbine flow meter can accurately measure the average velocity of a fluid as it travels through it.
The vaned rotor is found inside the meter where it is centred on a shaft and allowed to rotate on bearings. Tube bundles support the shaft, which provide an element of flow conditioning, aiding the accuracy of the reading.
The reason it is a great choice for water is its wide size range and excellent precision, as well as the ability to maintain ultrapure water. Litre Meter normally select a hard carbon composite bearing suitable for pH levels below 6.
