Product Description
Ningshui Length 110mm Single-jet Mechanical water meter Introduction
Ningshui Length 110mm Single-jet Mechanical water meter is a type of water meter that uses a single inlet port and a jet of water to drive an impeller or vane wheel, which in turn drives a mechanical register to measure the amount of water passing through the meter.
In a single-jet mechanical water meter, water enters the meter body through the inlet and passes through a nozzle that creates a single, focused jet of water that strikes the impeller or vane wheel, causing it to rotate. The rotation of the impeller or vane wheel is proportional to the flow rate of the water, and this rotation is transmitted through a magnetic or mechanical coupling to a mechanical register that records the total amount of water passing through the meter.
→ Single jet type, dry type register with magnetic transmission.
→ Hermetically sealed register with 360 rotation, and protected against external magnetic interference.
→ Optimum accuracy with very low starting flow rate.
→ Brass body and durable tamper proof construction.
→ Vacuum sealed register ensures the dial kept free from fog and keep the reading clear in a long term service.
→ Internal regulating device.
→ With high accuracy
→ For horizontal use
→ Measuring accuracy conform to ISO 4064 class B Standard
→ Selected high quality materials for steady & reliable characteristic
→ Universal use.Easy for interchange & maintenance
→ Long-life, low maintenance operation.
