RMG Ultrasonic Gas Flow Meter
RMG USZ 08 In line ultrasonic Flow Meter
USZ 08 Ultrasonic Gas Meters are designated for measuring and calculation of the volume and flow rate of natural gas, petroleum gas, propane, butane, and other gases at operating conditions.The operating principle of the meters is based on the measurement of the difference between the time of transmission of ultrasonic pulses along and against the gas flow. The time difference, as measured, proportionate to the flow speed is converted into the flow rate value.
USZ 08 Ultrasonic Gas Meter is a modern metering device that features high reliability, accuracy and stable operation. Big measuring range of the gas meter allows using it at gas stations having highly fluctuating gas flows.
Device for Custody-transfer Metering
- Suitable starting with absolute pressure pn = 1 bar
- High stability against turbulences thanks to 6 measuring paths in 3 levels
- Tested according to TR G13/OIML
- Air calibration with high-pressure test according to TR G7
- High flow rates (up to 40 m/s) – that means smaller pipe sizes may be used
- Exchange of sensors without recalibration
- High measuring accuracy
- Robust, dirt-repellent titanium sensors
- Easy operation using control computer with corrector function from flow computer Series ERZ 2000
- Design with dedicated meter and impulse outputs
- Diagnostic PC software RMGView
