(See page 71 of the user’s manual for Wiring diagramand2. 11.2 – 11.4 of Mercury Mini User’s Manual)If neither of these pulsers are being used it may be possible to get the utility to provide accessand enable the pulser for customer use. It comes from thefactory configured as either a Form A or Form C Pulse output and must be “enabled” throughthe Software (see Diagram 1, or, sec. Thisis an Opto-Isolated Pulse Output with a terminal block (TB1) for Wiring. 11.1 of Mercury Mini User’s Manual)They also will normally have at least one configurable Electronic Corrected Pulse Output. (see Diagram 1, or page 13, sec6.10 and, sec. There should be a terminal block on the MeterPulse (or Switch) Board that facilitates wiring to this pulser. This isgenerated by a magnet on a drive shaft from the instrument’s MechanicalUncorrected Index (UMB) passing a reed switch. For the sake of simplicity thisdocument will discuss the Mercury Mini Series.Most instruments come with Mechanical Uncorrected Pulse Output. They are typically used as Pressure (P) orPressure & Temperature (PT) Correctors. Models include the ECAT, MINIMINI-AT, and MINI-Max. The most prevalent Correcting Instruments in the Industry aremanufactured by Mercury Instruments. Using Existing Corrected and/or Uncorrected Output from a Correcting InstrumentThe easiest way is to simply take the Corrected Pulse Output from theInstrument. AMR Equipment (Automatic MeterReading): Metscan, Metretek, ITRON etc.CBADEFThere are a variety of ways to get pulse output from a meter and/or Correcting Instrument.1. Correcting Instrument(s): Pressure andTemperature Correctors (Mercury, Actaris,G.A.S, etc.)F. Thebest point of contact is the Local Utility’s Account Representative.A typical utility C&I meter set may consist of:A. Under no circumstances should an end-user or third partyattempt to interface with or modify the utility’s equipment without their consent and assistance. Adding Pulse Output to Utility’s Gas Meter – Commercial/Industrial MetersThis document discusses the technical possibilities for getting pulse output from a typicalcommercial/industrial meter set-up.
