Liquid counters screw PPV are intended for measurement of volume of nonaggressive (Newtonian) liquids with kinematic viscosity from 0,55 to 300 cSt with a temperature from minus 50 to plus 50 Celsius degrees, pressure up to 1,6 and 6,4 MPas.
Counters use in permanent technology units, and also on land mobile means of gas station and transfer during their work on site in the conditions excluding direct influence of solar radiation and an atmospheric precipitation.
The operation principle of screw counters of liquid reminds work of an extruder and is that two screws which are in gearing rotate under the influence of a fluid flow, measure some volume at each turn. Rotation of screws via the magnetic clutch, is transferred to the calculating mechanism, being transformed to unit volumes.
PPV counters are completed with the mechanical calculating device (CD) or the device of removal of signals (DRS) with the controller of the CLUMPS type with the electronic digital reading index of an instant, one - time and total consumption of liquid, also the panel of remote information transfer "Spring combined heat and power plant".
