RPM Series Rotary Meters Presented by Mike Javon Product Coordinator Industrial Products Business Unit
Principle of Operation Demand initiates gas flow through the meter Impeller captures a fixed-volume of gas
Principle of Operation Measuring cavity opens releasing gas downstream The meter cycles four times completing one revolution
RPM Series Rotary MeterCodes and Standards • ASME Boiler & Pressure Vessel Code: Section VIII • ANSI B16.5 Flanged Pipe and Fittings • ANSI B31.8 Gas Piping • ANSI B109.3 Rotary Gas Meters • Pressure Rating: 175 PSIG (standard) - 285 PSIG (optional) • Proof Accuracy: +/-1% • Operating Temperature: -40° to +140° F • 49 CFR 192 Min Federal Safety Standards • NSTA-1A Packaging
RPM Meter Features & BenefitsSuperior Strength • Heavy Duty Housings - Provides superior strength against bending or twisting from pipe stress.
Superior Strength 1.5M RPM Rotary Meter on Prover: 215 Pounds hand from a 6 foot schedule 80 pipe with NO affect on Accuracy/Proof. Effect of weight on pipe - Meter still running at Qmax !!
RPM Meter Features & BenefitsFlexibility • Flexible space saving design - All RPM Series Meters mount in either a vertical or horizontal position, depending on available space and convenience. All standard and optional equipment can be positioned easily for quick service and convenient reading.
Flexibility • Flexible space saving design - Reverse flowing register available eliminating the need for costly additional piping.
Flexibility • Flexible mounting of accessories - Regardless of the meter’s mounting position, the temperature compensator or correcting instrument faces the reader.
RPM Meter Features & Benefits • Mechanical Counter - All RPM Series Meters are supplied with a standard uncorrected mechanical register. The magnet driven register and its housing rotate in 90° increments to facilitate vertical or horizontal mounting of meter.
RPM Meter Features & Benefits • Mechanical Counter - The integral register is built of teflon and glass reinforced nylon material assuring quiet operation and protection against corrosion. All meters are supplied with the register’s low frequency pulse transmitter (piezo switch).
RPM Meter Features & BenefitsPulsers • Low Frequency Inductive Pulser - The low frequency pulser option
RPM Meter Features & BenefitsPulsers • High Frequency Inductive Pulser - The high frequency pulser option produces a flow rate signal that interfaces with popular flow computers. The computer scales the meter’s output and totalizes the volume.
RPM Meter Features & Benefits • Temperature Compensator - The RPMTC has six months of data storage and includes a port for downloading corrected and uncorrected volumes.
RPM Meter Features & BenefitsTemperature Compensator Setup Parameters • Device & Customer I.D. • Back-up date for History File • English or Metric • 4-8 Corrected & Uncorrected Digits Displayed • Base Temperature • Supercompressibility • Atmospheric Pressure • Base Pressure (Billing) • Inlet Pressure (at meter) for Fixed-Factor Measurement • Pulse Output Options • 2 Corrected/1 Uncorrected • 1 Corrected/1 Uncorrected/1 Alarm • Time Zone
