MJP-SDC  is  impeller  (turbine)  water  meter  with  dry  register  for  residential purposes. Sizes range from 5/8” to 1-1/2”, and the accuracy meets AWWA C708 standard, wet materials are NSF/ANSI-61 and 372 certified, NSF official listings as follows:



Operation:

 

Water flows through the meter’s strainer (inlet and internal) and into the measuring chamber where it drives the impeller. A driving magnet transmits the movement of the impeller to a driven magnet located within the sealed register. The magnet is connected to a gear train which translates the impeller rotates into volume totalizers displayed on the register dial face.


Construction:


MJP-SDC top loaded Water Meter consists of three basic components: main case, measuring chamber and a head ring. The main cases of all sizes are made of Reliable Polymer.


Characteristics:


  • All the Materials that’s in contact with water, are well-known materials with strong resistance to corrosion, and are NSF-61 certified;

  • The most Reliable Polymer from BASF for the body of the water meter;

  • Cold water meter under current standard for lower than 30(T30), but MJP-SDC can be used safely in water temperature up to 50(T50=122°F) ;

  • The impeller is the only moving parts that are in contact with water, allowin the most stability;

  • The extra inlet filter at the inlet of the meter body allows cleaning it without breaking thmetrological seal;

  • The conception of the Magnetic Protection to against the external influences;

  • Non Return Valve to avoid the reserve flow Rate AS OPTION;


 Dial Plate Design in USG (m3 and CF AS OPTION):

5+4 dial for 5/8”~1”              6+3 dial for 1-1/2

      


Dimension:   L1: the total length with connection and the gasket without compression.

 Pulse output pre-quipped or Pulse output installed:

 

  • Meter could be with magnet installed at the preferred position

  • Meter could be with the Pulse Emitter Device which consists of a plastic housing with single reed switch, and 1.5 m cable with 2 wires in Red and Black.

  • Option with double reed switches and 1.5 m cable with 3 wires in Red, Black and Blue;

  • Electric Data: Vmax=24AC/DC; Imax=0.1A

  • Capacity of the Pulse Emitter:


 


Installation Instructions


  • Thoroughly flush the service line upstream of the meter to remove dirt and debris.

  • Remove meter spud thread protectors.

  • Note: To protect meter spud threads, store the meter with thread protectors in place.

  • Set the meter in line. Install horizontally, with the register upright, in a location accessible for reading, service and inspection. Arrows on the side of the meter and above the outlet spud indicate the direction of water flow.

  •  For accurate measurement, the tap height should be higher than the meter.

  •  Do not over-tighten connections; tighten only as required to seal. Do not use pipe sealant tape on meter threads.

  •  With upstream shut-off valve only: Open shut-off valve slowly, to remove air from meter and service line. Open a faucet slowly to allow entrapped air to escape. Close the faucet.

  • With both upstream and downstream shut-off valves installed. To test the installation for leaking: Close the outlet (downstream) shut-off valve. Open the inlet (upstream) shut-off slowly until meter is full of water. Open the outlet (downstream) valve slowly until air is out of the meter and service line. Open a faucet slowly to allow entrapped air to escape. Close the faucet.


Maintenance/Repair

 

Preventative maintenance consists of periodic inspections and cleaning procedures. The procedures should be performed at regular intervals, and any defects discovered should be corrected before further operation of the meter.Visually inspect the meter for missing hardware, broken resister lens or other signs of wear or deterioration. Verify proper flow rate and pressure for meter. Loss in pressure which results in flow rate decreasing, may indicate the meter screen is clogged and requires cleaning. Clean the strainer yearly, or as required, depending on water condition. Pull out the strainer or back flush the meter to loosen trapped particulates.

The Series MJP-SDC is not field serviceable and should be returned if repair is needed or being repaired under our correct instruction.
