Info

Additional InstrumentationThe indicated volume will often be converted to volume atbase conditions. Parameters for these conversions might be:• PressureA pressure tapping enables the measurement of the staticpressure near the turbine wheel. The pressure measurementpoint P r (pressure at metering conditions), designated P m inthe latest standards, is located on the meter housing and ismarked. The bore is 3 mm and perpendicular to the wall.Connection with 6 mm stainless (standard) tubing or largeris recommended.• TemperatureThe temperature measurement should preferably be locatedwithin 3 D downstream of the meter. No pressure reducingparts should be located between the temperature deviceand the meter. The temperature should be measured withinthe center third of the pipe.• Actual densityWhen an actual density meter is used, the requirements forthe pressure and temperature should be followed for thelocation of the density meter. The P r point is the source ofthe gas sample for a density meter that should be located3-5 diameters downstream of the gas turbine meter.No devices that can influence the pressure or the temperatureof the gas should be installed between a gas meterand the applicable temperature sensor and/or densitymeter.Flow Converters andAdditional EquipmentVemm tec can provide you with flow converting devices,ranging from a converter with only basic features, to asophisticated computer with features such as curve correction,valve control, gas chromatograph read-out and othercustomer specified functions.We can also provide you with the additional equipmentsuch as IS-barriers, F/I-converters, transmitters, filters,straightening vanes and meter tubes.We will be happy to send you any further information.SystemsVemm tec has many years of experience with meteringskids such as provers or pressure reduction stations. At yourrequest we will be happy to offer meter runs and integratedsystems.Ordering InformationIn order to quickly process your enquiry, we need the followinginformation for adequate pricing and sizing:· Nominal pipe size in mm or inches for installing the meter· Model: High accurate custody transfer type (CT) or industrialmodel (IM)· Body material: Ductile iron, carbon steel or stainless steel· Flow rate: Maximum, minimum (actual or standard cubicmeter per hour, please specify); or G-size.· Pressure: Maximum, minimum and normal operatingpressure· Temperature: Maximum, minimum and normal operatingtemperature· Gas type, composition or analysis (if available)· Relative density or base density (standard conditions)· Flange connection, pressure rating and face type· Output signals required (LF reed switch, HF at index heador HF at turbine wheel, dual pulse output)· Installation conditions (Indoor-Outdoor, ambient conditions)· Flow direction horizontal (left-right; right-left) or vertical(up-down; down-up)· Optional services and additional equipment required (calibrations,barriers, flow correctors, filters, meter tubes)Alternatively you can ask for our IGTM questionnaire.8
