Gear Flow Meters, High Precision
Beda Flow Systems, the Indian subsidiary of German E-Holding Fluid Technology Group provides specialised fluid technology solutions to automotive, hydraulic, dyes and paints, plastics and chemical industries in India using high precision VSE gear flow meters. These are volume rate measuring sensors based on mesh gear principle and are designed for use with any liquid that can be pumped and have known lubricant properties, e.g., Petrol, Paraffin, kerosene, diesel, skydrol (Jet-fuel), mineral oils, hydraulic oils including fire resistant fluids, inks, dyes, paints, greases, polyurethane, polyol and isocyanates, Araldite, glues, pastes and creams, resins, waxes, etc. Working principle: two precisely matched gear wheels are enclosed in a very accurately machined housing. Gear rotation is sensed by a non-contacting signal pick- up system. Each tooth produces one impulse. The space between the gear teeth, when fully enclosed on both sides by the housing, constitutes measuring chambers. Fluid flow causes the gears to rotate and the incoming flow is separated into discreet volumes with in these chambers, i.e., the volume of liquid passing thru the unit will cause rotation of the gears by exactly one tooth pitch. This volume is known as the volume/impulse and is stated in cc/Imp. It is used to define the size of a flow meter. Applications in automotive industries: fuel consumption in auto engines; and on test benches for – braking system, power steering systems, leakage testing; PU application – seating fascia manufacturing; paint spraying systems; batching, filling of motor oils, brake fluids; and adhesive coatings for windscreens, headlights.
