The MQMe quantometer is based on the principle of a turbine flow meter with an integrated electronic index head. The MQM is designed for flow and volume measurement for natural gas, nitrogen, air (and other gases on request) in non-custody transfer and process applications. The MQM is available in sizes from DN 25 (1´´) to DN 150 (6´´) with a volume flow rate up to 1600 m3/h depending on meter size. The meter housing is made of high strength aluminum. Itis designed as a sandwich construction (installed between two flanges). A volume correction function (AGA NX-19) can be optionally integrated in the electronic index head. Several communication options are available for data transmission: RS 485, M-Bus, Modbus, HF and LF signal as well as a 4 to 20 mA output. On a standard basis the MQMe meter is battery powered with a calculated battery life time of 5 years under standard conditions. 

Characteristics

• several options to transmit the measured an calculated data to a digital control system (DCS) or SCADA
• equipped with alternatively RS 485 or M-Bus interface and one high frequency (HF) as well as one low frequency (LF) pulser
• if an external power supply is connected to the MQME one 4 to 20 mA configurable signal is available
• the rotation of the rotor can be scannes additionally with one external high frequency (HF) sensor
• the HF-sensor signal allows the determination of the actual gas flow in high-resolution and can be transmit to any digital control system (DCS) or SCADA for flow control purposes
• integrated electronic volume corrector
