ZV flow indicator is available in two versions, with an exchange  electrical  contact  or with  a proportional voltage or current. The operating  point, in the electro-mechanical version, is reached  sliding along the axis of the instrument the connector’s saddle and locking it with an M3  screw. In the execution with proportional output  the connector is fixed in factory.
