LITRE METER SUPPLYS HOFFER METERS WITH CUSTOM SUBSEA DISPLAY

Litre Meter has received fresh orders for Hoffer Flow Controls (www.hofferflow.com) turbine flowmeters complete with custom displays developed in-house. The display, developed by Litre Meter, is designed for use in subsea installations and can operate at depths of up to 600 metres. This means that operators of ROVs can view the instrument while working on maintenance procedures subsea. It is easier for ROV operators to read the instrument in situ rather than wiring up the meter for surface viewing. The instrument features a customised flow rate indicator fitted to a standard turbine flowmeter. The display is mounted on pillars inside a stainless steel cylinder with Perspex viewing plate. Litre Meter CEO Charles Wemyss explained: ?These turbine flow meters are designed to operate at high pressures in harsh conditions. However, Hoffer needed a suitable display to go with its meters that could also operate effectively in these conditions. ?As a Hoffer distributor, Litre Meter was approached to use its expertise in subsea meter customisation to develop the instrument. ?Subsequently we have received a number of orders for these meters. ?There are several reasons why companies opt for customised meters but the most important is the ?bottom line? ? the amount that can be saved in costs. ?It is well worth talking to instrument manufacturers about available customisation options before seeking to ?make do? with a standard instrument that does not fully meet the needs of the application.? Hoffer manufactures high precision turbine flowmeter technology for the measurement of clean liquids and gases throughout the processing industries. The inline 'axial' turbine flowmeter measures the average velocity of a fluid flowing through the body of the meter. Mounted within the body of a turbine flowmeter is a vaned rotor centred on a shaft which rotates on bearings. The shaft is supported in the housing by tube bundles that also provide some flow conditioning for the fluid stream. Hoffer meters have a wide size range that can accurately measure flows of 0.25-20 litres/min up to 3,000-57,000 litres/min. Excellent accuracy provides an overrange of 150 per cent of maximum flow (intermittently) and ±0.25 per cent of the reading with a typical ±0.1 per cent repeatability.
