Additional changes are being proposed for 2013. and permits/wsforms.shtmlNote Concerning AMR Development, Remote Receptacles and Neptune MetersDEP is 97% complete in deploying an Aclara RF fixed network AMR system. Meters installed under permitshall continue to include the installation of a remote receptacle for the present, however, licensed plumbers arereminded that all three wires must be properly connected at the register head to allow simple installation ofan AMR box. Neptune meters must have an E-Coder register head factory programmed for use with an Aclarastandard MTU.

Systems withintermittent operation booster or hydro-pneumatic pumps which operate primarily on street pressure shall usecompound, single-jet or electromagnetic meters. Electronic meters are acceptable as an alternative to a turbinemeter. This category of meters should be sized based on the flow rate (gpm) of the house pump(s).COMPOUND/VARIABLE FLOW METERS - REQUIRES APPROVED OEM STRAINERBadger Recordall with ADE register (EnviroBrass II or Bialloy) . .2”  to  6”Neptune Truflo Compound w/ E-Coder . 2" to 6"Neptune 6"x8" Tru/Flo Compound Assembly . 8" onlySensus  Omni  C2 .1½”  to  6”Compound meters are not to be used for buildings with house pumps and a roof tank and any other applicationwhere flow rate is never below 5 gpm. Single-jet and electronic meters are acceptable alternatives tocompound meters. Note: DEP is proposing to end approval of compound meters in 2014.NOTE 1: Turbine  meters  6”  to  12”  must  have  a  registration  that  measures  in  100  cubic  foot  units.NOTE 2: The Hersey MVR vertical turbine and Sensus Omni meter have an internal strainer and do not requirean external strainer.2

The meter setting layout shall be the same as a compound or turbinemeter, except that Metron-Farnier single-jets do not require minimum straight pipe lengths before and after themeter. Single-jet meters must be installed in a horizontal plane. Aquamaster and TRU/MAG meters must beprovided with a source of electric power by the property owner and wired to power as part of the installation.Single-jet and Elster electromagnetic meters are both acceptable alternatives to compound meters and allelectromagnetic meters are also an acceptable alternative to turbine meters. The  terms  “Electronic  andElectromagnetic”  are  synonymous.METERS  TO  USE  TO  AVOID  “CALIBRATION  IN  PLACE”Turbine and compound meters with a strainer generally require straight pipe equal to five pipe diametersupstream of the meter and three pipe diameters downstream. Installations up  through  6”  that do not meet thisrequirement shall make use of the following technologies that do not require the same minimum straight pipelengths before and after the meter:If the application is constant flow (traditionally a turbine meter):Hersey  Vertical  Turbine  MVR  1”  – 6” (No straight pipe required)Elster  evoQ4  1½”  – 12”    (No  straight  pipe required)Sensus Omni T2, F2 1½”  – 6”  (Only  2.5  pipe  diameters of straight pipe before and after are required)If the application is variable flow (traditionally usually uses a compound meter):Single-jet meter (Metron-Farnier)  up  to  6” (no straight pipe required)Elster evoQ4 2”  – 10”    (No  straight  pipe  required)Sensus Omni C2 1½”  – 6”  (Only  2.5  pipe  diameters of straight pipe before and after are required)FIRE SERVICE METERS - REQUIRES FM/UL APPROVED STRAINERElster evoQ4 (Fire  Service  Model)   . .3”to  12”Elster Aquamaster (FM/UL Model) .10” Badger FSM w/ ADE register .        3”  to10”Badger  FSA  w/  ADE  register .4”  to 12”Neptune HP Fire Service Turbine with E-Coder  register   .3" to 10"Neptune Trident Protectus III with E-Coder  register .4" to 10"Sensus  Omni  F2 .4”  to 10”Metron-Farnier Enduro (turbine-type applications) . . . .6”  and  8”Application Notes: Fire  Service  Meters  are  to  be  installed  only  on  services  3”  and  larger  that  provide  bothdomestic and fire service. Dedicated fire services should have a detector backflow device as approved by CrossConnections Control. Turbine FSM’s are to be used only for applications with a relatively high demand profile,generally only services which feed house tanks or other pumped distribution systems if required by the BuildingCode. Compound versions are to be used in applications without house pumps. The Aquamaster Fire ServiceModel and evoQ4 do not require a strainer. Aquamaster meters must be provided with a source of electricpower by the property owner. The evoQ4 and Aquamaster can substitute for turbine-type and compound-typeFSM’s. Fire-rated electronic meters can be installed on domestic services without fire sprinklers.3

DETECTOR ASSEMBLIESAn approved displacement meter with an encoding register and remote receptacle is required on the bypass andshall be 3/4" in size. Lists of approved backflow equipment can be found in the  “Revised  New  York  City  DEPSupplement  to  the  New  York  State  Department  of  Health  (DOH)  Handbook  for  Cross  Connection  Control” and permits/backflow.shtmlMETERS APPROVED FOR COMBINED FIRE/DOMESTIC SERVICESWhere  the  term  “combined  service”  is  used  here  it  describes  any water service that supplies both domesticneeds and any number of fire protection sprinklers.For 1" and 1½" combined services:Alternate 1:Alternate 2:Electronic meterSingle-jet meter as long as installation is horizontal /- 10 degreesFor 2" combined services not flowing to house pumps or fire service pumps:Alternate 1:Alternate 2:Alternate 3:Electronic meterSingle-jet as noted aboveDisplacement meter on domestic branch and detector check valve assembly on thefire branch.Note:2½”  combined  services  shall use upsized equipment and shall adhere to therequirements  for  3”  combined  services.For  2”  and larger combined services to pumps/house tank or fire service pumps:Alternate 1:Alternate 2:Alternate 3:Turbine meter (3” and larger) one meter for the entire serviceElectronic meter (2”  or  larger) one meter for the entire serviceIf there are two distinct branches separating within view of the point of entry, adomestic meter can be placed on the pumped domestic branch and detectorbackflow prevention device on the fire branch.For 3" and larger combined services not flowing to house pumps:Alternate 1:Fire service compound, FM-rated electronic or electromagnetic meter at head ofthe combined service.Alternate 2:Double detector check valve assembly on the fire service branch and a domestictype meter (positive displacement, electromagnetic, single-jet or compound) onthe domestic branch.METERS APPROVED FOR EVAPORATIVE COOLING TOWERSDisplacement, single-jet, electronic or turbine meters. Make-up water meters for evaporative cooling towersthat are used for the calculation of a wastewater allowance are the property and responsibility of the propertyowner or their agent. Make-up water meters for cooling towers which are used for direct billing by DEP are theproperty and responsibility of DEP. In either case, the remote receptacle must be placed on an exterior buildingwall for placement of an AMR MTU.4

METER STRAINERSOnly flat-plate or  “z  plate”  strainers from the meter manufacturers are approved, except for products notedabove which have internal strainers, or FM/UL-rated strainers for fire service meters.HOT WATER METERSHersey Vertical Turbine (hot water version), reading in cubic feet and equipped with Translator Encodedregister and remote receptacle . ¾" to 2"Metron-Farnier Spectrum w/Innov8 Register (Rated to 140 ) .¾”  to  2”Application notes: Hot water meters shall be approved for billing purposes only under the following conditions:1.Large consumers (over 200 gpd) of hot water from a central boiler plant (e.g., laundries or foodestablishments) which are located in residential buildings
