Counters of liquid fuel of the VZO 4 series are intended for measurement and the accounting of a consumption of diesel fuel in torches, diesel generators, on motor transport, tractors, agricultural, construction and other special equipment, on all engines the power of which does not prevysht 250 hp.
Operation of counters is based on the volumetric principle of measurement (rotary progress of a volumetric glass in the camera of the brass case). The device works without external power supply. Loss of pressure in the device does not exceed 0.17 bars that allows to use the counter in free-flow systems i.e. where fuel moves even spontaneously.
The standard model - the device with the mechanical roller calculating mechanism, can be equipped with the pulse sensor in addition. Model with the OEM index - without roller calculating mechanism with the gerkonovy pulse sensor. It is necessary to use the VZOA counters passing special mutual calibration to optimum result of differential measurements.
The counter is compact, it is easily and conveniently mounted, not demands additional service. For horizontal, vertical and inclined installation. Counters with indication - the case from brass with the calculating mechanism, closed by a translucent plastic cover, without indication - the case from brass with gerkony on the top surface.
