Operations:

FLOW multijet is a velocity type inferential water meter. Water enters into the measuring chamber through specially designed holes, which directs the flow at the turbine equally from several points around its circumference; minimizing uneven wear on the turbine and its shaft. Water moves out from the chamber through a different set of holes to the outlet. The number of performed turns of the turbine is proportional to the volume of water passing through the meter. A drive magnet transmits the motion of the meter. A drive magnet transmits the motion of the turbine to a driven magnet of the dial register, housed in a strong upper chamber. The driver magnet is connected to a gear train which translates the turbine’s rotation into volume totalization displayed on the counters. An external regulator mechanism is provided to adjust and fine tune the accuracy within excellent limits.

Features
  • • The Total Internal mechanism is sealed using gaskets and rings to the brass body and covered using a robust registration brass cover to avoid water seepage making it Moisture proof, dust free, waterproof.
  • • Its unique anti-reversal flow construction restricts reverse flow and does not record reading.
  • • The counters designed simple and precise, read in Kilo Litres and litres in circular pointers.
  • • Start wheel in the middle shows turbine movements at the lowest flows and can be used to detect leakage.
  • • Tamper-resistant construction: Meters cannot be tampered without breaking seal.
  • • Light weight turbine pivoted perfectly on a highly polished non magnetic SS Pivot keeps in perfect symmetrical balance and avoids friction and tension in turbine movement.
  • • High quality sapphire jewels bearing provided for low flow start-up and superior low flow accuracy.
  • • High quality UV additive virgin engineering plastics used for manufacturing of components, prevents degradation over long period even in worst environmental conditions.
  • • Superior flow rate accuracy and greater stability in high flow rates.
  • • Not sensitive to particulates in the water. The inner case protective cover design prevents foreign particles to simply pass right through, causing no damage to the meter.
  • • Protective chambers restrict and designate the flow and protects the turbines from direct impact of water force.
  • • Pulse output facility provided with a 10ltr/pulse for advanced AMR Application.

AMR Module

The FW01A Series AMR(Automted Meter Reading) is compatible with all the predisposed multiple jet meters (wet dial, semi-dry dial, dry dial), uses the LoRa standard and is compliant with the LoRa WAN protocol*. It has been designed to allow wireless remote reading in different types of applications from the residential sector to the commercial and industrial sectors. The radio module thanks to the presence of the magnetic pointer on the counter and can offer the following functions listed below and allows the reading of the counter without constraints of access to the site in direct reading mode or AMR (automatic meter reading).
