The Liter counters volumetric Oval Wheel VZS is ideal for measuring oils, hydraulic fluids, motor oil and lubricants, fuels, diesel. Are used for measurement of low flow rates in dosage or for testing engines.
The stainless steel AISI316 and seals in Viton and Teflon, making it suitable for chemically aggressive media.

The Liter counters VZS uses two wheels mesh with a fine toothed oval shaped that damage to ensuring a high precision working.
The fluid is transferred sequentially from input to output and one or two pulses are transmitted for each turn of the wheel. Inside the meter there is a pair of magnets chemically resistant that have the task of formire outside the signal.

For detection of the rotation is used or a switch or a reed sensor affection Hall placed outside the meter and therefore not in contact with the fluid.
The choice of materials of construction, 316L stainless steel, PPS, PTFE, allows the customer to use it in a variety of applications with corrosive liquids and viscous.
