Impulse sensor IS-09

Impulse sensor IS-09 is during its operation inserted through hole for NF output in a lid of gas meter into space of dial drive and its position is ensured by adjusting screw in arresting slot. Realization of variable magnetic field is realized by rotation of additional dial wheel of gas meter with eccentrically attached roller of permanent magnet.

Additional wheel is driven by the same toothing as is the whole gas meter dial and therefore is secured its synchronous operation. The number of revolutions of additional wheel on 1 m3 measured volume by gas meter is consistent with the number of revolutions of the last dial wheel. Additional wheel has opposite direction of rotating than has dial of gas meter.

Gas meter is being certified with inbuilt sensor.
