Measuring device description
The CMD1687SK-G fuel dispensers are designed for measurement of liquid fuel volumes and are used for the refuelling of motor vehicles, small boats and small aircrafts.
The CMD1687SK-G measuring system consists of a pumping unit with incorporated gas separator, measuring transducer, electronic calculator with indicating device (display) and electronic totalizing indicating device, electromagnetic valve, sight glass (optional) and hose with delivery nozzle.
This fuel dispenser is equipped with pre-setting device. Pre-setting of a volume or price value is done by keyboard on the electronic calculator.
This measuring system can be made as pressurized system in centrally pumped system or with external submersible pump. In that case the installation of a gas separator is NOT mandatory. If it is not intended to install a gas separator, the design of installation has to ensure that there is no risk of air intake or gas release.
Designation of a fuel dispenser series:
CMD1687SK-G (nul, A, B, C) (1, 2, 4, 8) (1, 2, 3, 4, 6, 8) (null, Q),
