Litre Meter supplies EFC with gear meters from sister company KEM

10 June, 2016

KEM ZHM gear meters can measure fluids in a flow rate range of 0.005 up to 1000 l/m. Fluids can range in viscosity from 5 to 25,000 mm2/s (cSt). Linearity is plus or minus 0.5 per cent of the actual value with a repeatability of plus or minus 0.1 per cent. The meters are designed to work at pressures of up to 630 bar at a maximum temperature of 180degC.

The robust ZHM KL gear meters are designed specifically for measuring lubricating and non-abrasive fluids such as oils and greases. Parts are manufactured exclusively of high-grade stainless steel, making them well suited for middle and high pressure media.

Various design sizes of the ZHM KL flowmeter series allow a wide range of applications including consumption measuring, monitoring, mixing and dosing. Due to precise ball bearings, optimal measurement accuracy and good dynamic characteristics are claimed to be guaranteed.

Gear flowmeters are positive displacement volumetric counters with an internal design similar to a gear pump. There are two gear wheels inside the flowmeter body which engage with minimum play in a closed measuring chamber between the gears and their housing. The revolutions per minute (rpm) of the gears are proportional to the instantaneous flowrate.

The fluid to be measured is forced through the meter chamber and turns the gears, which move freely in order not to break the flow. The rpm of the gears as the fluid passes through the chamber is picked up and measured using contactless sensors through the body wall.

The KEM ZHM-KL flowmeters also feature high output frequency, short response time, reverse flow detection and pulse multiplication. The meters are ATEX approved and rated to Ex IA IIC T4 or T6 for zone 1 (where gases, mists or vapours are likely to occur).
