Waste Water and Industry Effluent

Here at Litre Meter, we specialise in flow meters. We design, manufacture and supply a wide range of reliable measurement solutions to suit a number of materials and jobs. 
All fluids have different characteristics; this means some are better suited to certain flow meters than others. The best flow meter for the job is dictated by the flow’s properties, including its given pressure, temperature, density, conductivity and composition, to mention only a few.
We offer quality flow meters that accurately measure the flow rate of all kinds of liquids and gases, including waste water and industry effluent – mainly used for safety, health and hygiene purposes.
See our range of flow meters suitable for waste water and other industry effluent below:
Turbine
Turbine flow meters are one of our specialities here at Litre Meter. As a versatile measuring solution, a turbine flow meter is used for calculating the average velocity of a wide range of fluids and gases. 
To do this, it uses a vaned rotor which rotates on a shaft. The shaft is also supported by tube bundles which provide a degree of flow conditioning for the fluid, improving the accuracy of the reading. 
Its precision as well as its wide size range makes it a great choice of flow meter for a number of jobs.
Vortex
Along with all oscillatory flow meters, vortex shedding determines a fluid’s velocity and rate by detecting provoked vortices made from the fluid itself. 
Vortex shedding calculates the volumetric flow rate by using the fluid’s own properties – such as its pressure, density and viscosity – to induce the fluctuations that create these vortices. 
With the ability to measure low viscosity and volumetric flow rate, vortex shedding has been found to be one of the best choices to accurately measure water, as well as other forms clean or dirty liquids, gases and steam. 
Ultrasonic
Ultrasonic flow meters are used to determine the flow velocity. They do this using ultrasonic waves that pass through the flow, measuring the travelling times or the frequency shifts. 
There are two types of ultrasonic flow meters to choose from; clamped-on and inline. They differ by the way they are installed, but both require a simple process.
This is a particularly good flow meter for measuring water as well as other liquids, and can also measure a certain amount of solid content.

Vortex Vortex and other types of "oscillatory" flow meters utilize the behaviour fluid oscillations in order to derive flow rate. This technology works by inducing fluctuations in the fluid properties such as pressure, density or viscosity which can be converted into a flow rate. These flowmeters are normally calibrated on water. No moving parts and relatively tolerant to particulate flow these find many applications where temperatures are high or where other more traditional flowmeter technologies are out of spec. +/- 1.5% rate, 1/2" to 8" and insertion.
Ultrasonic Ultrasonic flowmeters measure the travelling times (transit time models) or the frequency shifts (Doppler models) of ultrasonic waves in a pre-configured acoustic field that the flow is passing through to determine the flow velocity. The Sierra range of ultrasonic (transit time) Innovasonic devices are available, click for details. Litre Meter has access to other ranges but the Innovasonic is relatively unique as not only are fixed and portable ultrasonics available but also insertion devices for tougher applications. Ultrasonic flow meters can measure water and other liquids over a range of velocities and with a certain amount of solid content. 25mm to 10000mm;±1.0% of reading (also 0.5%); 0 to ±40 ft/s (0 to ±12 m/s).
Turbine Inline 'axial' turbine flowmeters are velocity measuring devices - they measure the average velocity of a fluid flowing through the body of the meter. Mounted within the body of a liquid turbine flowmeter is a vaned rotor. The rotor is centred on a shaft and allowed to rotate on bearings. The shaft is supported in the housing by tube bundles that also provide a measure of flow conditioning for the fluid stream. Good for low viscosity flow metering. Wide size range and excellent accuracy. 0.24-17 up to 3028-56775 litres/min. Overrange 150% intermittent. ±0.25% reading - typical. ±0.1% repeatability.
