The measurer

Also called the measuring chamber, this is the heart of the counting system. The meter measuring chamber (1) is formed by 3 cylindrical bores (2). Three rotors, the locking rotor (3) and two vanes (4.5) rotate synchronously inside the bores. The three rotors are supported by flanges (6.7). The rotors are driven with each other by sprockets (8,9 and 10).

As fluid flows through the meter housing, the rotors rotate and separate the fluid into uniform sections. We thus obtain an identical cyclic volume at each revolution of the rotor. It is thus possible to determine the exact volume of the liquid which passes through the meter. The meter or measuring chamber can be equipped with different such as: Filter (at meter inlet), Gas separator purger.

The adjuster

It transmits the mechanical movement of the measuring chamber to the indicator. It is a mechanical assembly placed between the measuring element and the indicator, allowing the adjustment of the precision of the counter. An error can be corrected by a simple micrometric adjustment over a range of 5% (in units of 0.02%, 0.1% or 1%).

The display

It retransmits the measured volume and converts it into an indication that can be read and used by the operator. The mechanical indicator can also be fitted with the following options: dose preselector, ticket printer, pulse transmitter (for remote reporting).
