Flowmeter Application Guide

 

 

Different measurement applications demand different measurement principles and the following is a guide to Litre Meter Flow Measurement Products.

 

LOW VISCOSITY LIQUIDS

 

Pelton Wheel (turbine type for all liquids)

 

 

Euromag Electromagnetic (conductive liquids)

 

HIGH and LOW VISCOSITY LIQUIDS

 

Helical Screw (positive displacement)

 

 

Euromag Electromagnetic (conductive liquids)

 

 

Rotary (positive displacement)

 

DIRTY LIQUIDS

 

Euromag Electromagnetic (conductive liquids)

 

FLUIDS IN HAZARDOUS AREAS

 

Pelton Wheel EEx ia IIc T5 Intrinsically Safe for liquids

 

 

Helical Screw EEx ia IIc T5 Intrinsically Safe for liquids

 

 

Rotary EEx ia IIcc T4 Intrinsically Safe for liquids

 

 

Thermal Mass Gas Meters - explosion-proof CENELEC EEx d IIc T6-T2

 

AGGRESSIVE LIQUIDS

 

Pelton Wheel Meters in All-plastic - PFA (Teflon), PVDF, PP or PVC with sapphire bearings

 

 

Euromag Electromagnetic Flowmeters with chemically resisitant liners and electrodes in titanium, tantalum, platinum or hastelloy (conductive liquids)

 

HIGH PURITY FLUIDS

 

Pelton Wheel Turbine Flowmeters in All-plastic - PFA (Teflon) with sapphire bearings for liquids

 

 

Sierra Thermal Mass Gas Flowmeters type UHP - Ultra High purity

 

STEAM

 

Sierra 'Innova-Flow' and 'innova-Mass' Vortex Meters

 

GASES - Sierra and Ritter

 

Sierra Small Thermal Mass Gas Flowmeters and Flow Controllers 0-0.4 SCCM to 0-500 SLM

 

 

Sierra Thermal Mass Meters with bodies to 8" (200mm)

 

 

Sierra Insertion Thermal Mass Gas Flowmeters for pipes, ducts and stack emissions

 

 

Ultra High Purity and Hazardous Area versions available

 

 

'Innova-Mass' Vortex meters for High pressures

 

 

 

HIGH PRESSURE FLUIDS

 

Pelton Wheel, Helical Screw and Rotary Meters for pressures up to 2068 bar including Intrinsically Safe for Hazardous Areas (developed for off-shore industry). VFF meters to 4000 bar.

 

FOODSTUFFS

 

Euromag Electromagnetic Flowmeters (conductive liquids)

 

 

Pelton Wheel (turbine type)

 

NON-INVASIVE FLOWMETERS

 

Where it is desirable that a meter should be mounted externally on the pipeline, an ultrasonic flowmeter can often be employed. It can be used for line sizes from 6.5mm to 6.5m bore. It is cost-effective for large bore installations and it is also portable
