The movement is mechaically transmitted to the totaliser.
Key Benefits
- High accuracy and rangeability budget meter
- Very low pressure loss
- No infl uence of installation conditions nor stop-and-go fl ow rate on the accuracy
- Protection class IP67 9-digit mechanical totaliser
- Various options available: Cyble Sensor, high frequency transmitter, thermowell, etc
Applications
Delta QD are designed to measure natural gas various filtered and non-corrosive gases as well as compressed air.
Due to the volumetric principle of the Delta QD, its metrology is not influenced by installation conditions.
Consequently, it can be used to build very campact stations without installing a straight pipe inlet before the meter.
They have been especially designed for industrial use and for secondary measurement and are particularly adapted when the flow can be low or irregular.
