ЛК-15ИХ, ЛК-15ИГ
Impeller Meters for
Cold and Hot Water
with Pulse Output

The ЛК impeller water meters with a pulse output are designed to measure the volume of potable water or hot water in the systems of hot water supply which flows through them at a maximal pressure of 1 МPa and for temperatures from 5 °С to 30 °С and from 30 °С to 90 °С with a rotating counting mechanism for convenient reading in any position. The meters are equipped with a reed-relay transducer of a “dry contact” pulse output to transmit a signal to the reading device.

The hermetically sealed counting mechanism of the meter excludes sweating and ingress of dust. The NOVATOR water meter has a built-in non-return valve which is designed to protect the meter against a reverse water flow, this excludes the possibility of water losses. The original solution of design and manufacturing technology of non-return valves makes the NOVATOR water meter simpler than other types.

The meters are equipped with the counting mechanism which has a magnetic link with the impeller device. Impeller suspension: ПАС agate jewels or ПКС corundum ones.

The materials of the parts contacting the running water are made of polypropylene 01020-16, do not deteriorate the water quality and are proof against its action. Body: ЛЦ40С brass. Service life: 12 years. Guarantee: 18 months from the date of putting into service.

The ЛК-15И water meters are proof against the influence of a magnetic field with an intensity of 50–100 mТ in conformity with the conditions of ДСТУ 3580-97.
