Litre Meter specialise in the design, manufacture and supply of flowmeters. The unique Pelton wheel based meter design ensures an inherent reliability which has been proven in more than three decades of operation. The VFF rotary piston flowmeter is used throughout the world for chemical flow measurement. Within the range of flowmeters that we distribute are the Sierra, Hoffer and Ritter flow meters. Sierra are the only flowmeter company in the world who manufacture capillary mass flow meters as well as industrial insertion meters based on thermal flowmetering principles. Hoffer manufacture turbine meters for gas. Ritter only manufacture gas meters including the laboratory grade TG series and Bellows Gas meters. Listed below are all the flow meters within our range that are suitable for liquids and gases found in food and beverage production and distribution:
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).
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 gas 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 gas flow metering particularly at higher pressures. Wide size range and excellent accuracy. 0.15 to 3.5 up to 200 to 12,000 ACFM. ±1% reading - typical. ±0.25% repeatability. Good for water 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.
From the stringent hygiene requirements of the manufacturing process to simple dispensing measurement at point of sale the industry relies on flow measurement. The Digmesa range of technologies offer cost effectives solutions for many applications. Whether you require beer or cold drinks dispensing, cellar auditing systems, coffee makers (industrial and domestic) or flowmeters for vending machines these meters can help. Ideally suited for low pressure process liquid flow measurement using plastic bodies from Arnite, PEEK or PVDF. From about 30 ml/min to 30 litres per minute. Contact factory for details. MOQ 100 units. +/-2% reading, +/-0.25% repeatability.
