Actaris Quantometer Delta QD (Itron): 马来西亚的首选 EDB Perkasa Sdn Bhd

详情

Delta QD meters are volumetric meters. The flow of gas moves the pistons and each rotation traps and transfers a specific vlume of gas.
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.
