APPLICATION: To totalize the total volume of cold (hot) water passing through the pipeline.
WORKING CONDITION:
The max.admissible water pressure: 1.0MPa.
Water temperature: 0.1℃~50℃.
FEATURES:
--Model LXF water meter is combined with a woltmann meter and a bypass multi-jet liquid sealed type meter.
--Basis of the volume of flow. The current flow out small-bore water meter or flow out both big-bore water meter and small-bore water meter by strength conversion installation. --The measuring range is very Wide, low starting flow with high measuring accuracy. It can measure accurately under low flow rate. It is suitable for conditions of protean flow rate.
--Selected high quality materials for steady & reliable characteristic;
Working principle
The piping water enters into the water meter from the inlet of the meter. According to the current, if the current is little, it is amounted by the small-bore water meter. If the current is up to the certain data, the strength conversion installation will control the current to make it flow into both big-bore water meter and small-bore water meter. The rotation of the helix turbine is transmitted to the clockwork through the worm gearing and the magnetic steel.The sealed register totalizes the rotation of the helix turbine and indicates the water volume passing through the meter.
MAXIMUM PERMISSIBLE ERROR:
From transitional flow up to maximum flow both inclusive: ±2%;
From minimum flow inclusive up to transitional flow: ±5%.
