Multi Jet Brass Water Meter


Measuring the total volume of cold portable water passing through the pipeline.



Working Principle

The Multi Jet meter operates on the velocity principle, that the water enters thorough the inlet and penetrate through the multi holes of the impeller cup and drives the impeller. The impeller is suspended by hydrodynamic forces to give minimum load on the bearings. The impeller rotation is magnetically transmitted to the register which the reading is made.

Construction of Material

Apollo Multi Jet Brass Meter body and connectors made in High grade Brass metal with CNC Machining to maintain the accuracy of the dimension which is major criteria for the accuracy of the Brass Meters.


  • Multi-jet, dry dial, easy for maintenance
  • Magnetic drive reliable characteristic, long working life
  • Vacuum sealed register ensures the dial keep free from fog and frost, Keep the reading clear in a long term service
