LITRE METER SUPPLIES ULTRA HIGH PURITY SIERRA METERS

Custom flow meter manufacturer and distributor Litre Meter has shipped a range of Sierra Flat Trak 780S-UHP Ultra High Purity units to a leading specialty gas supplier.

Speciality gases can range from 99.995 per cent to 99.99998 per cent purity depending on the gas type. To mix gases with this level of purity it is essential to use a robust electro-polished meter capable of high accuracy.
The Flat Trak-UHP instruments are designed to measure the flow of gases at pressures of up to 8 bar. The meters were selected because they are highly stable and deliver a measurement accuracy of +/- 1 per cent of reading plus 0.5 per cent of full scale and a repeatability of +/- 0.2 per cent of full scale. They also feature Sierra”s unique dual-plate flow conditioner which dramatically reduces straight run requirements.
The 780S-UHP is constructed with 316L electro-polished steel tubing in a choice of 7-10 Ra (UHP) or 20-25 Ra (HP) interior in pipe sizes from ½ inch up to 12 inches which are offered with Buttweld connections and a VCR probe-connection fitting.
Each meter is hazardous area-approved by CSA and CRN (Canada), FM (USA), ATEX, CE and PED (EU), IEC Ex (Australia), GOST R (Russian Federation) and Chinese Pattern Approval (China). The meter can therefore be used in hazardous clean area processes almost anywhere in the world.
Flat Trak features a versatile microprocessor-based transmitter which integrates the functions of flow-range adjustment, meter validation and diagnostics in a probe-mounted NEMA 4X (IP65) housing. Mass flow rate and totalised flow, as well as other configuration variables, can be displayed on the meter”s optional 2 x 12 backlit LCD panel.
Litre Meter, a leading manufacturer and supplier of custom flow meters, is the UK distributor for the Sierra Instruments range of flow meters. As with Litre Meter”s own range of custom flow meters, Sierra Instruments” range is designed to operate in some of the harshest conditions on the planet.
