General information about the measuring device
The FLOWSIC900 F9L-XXXY is an ultrasonic flow meter for measuring the volume of liquified natural gas (LNG) and low viscosity oil. It is based on the measurement of the runtimes of ultrasonic pulses along several measuring paths. The meter consists of the following assemblies:
One meter body with a straight pipe section with 4 or 8 ultrasonic measuring paths.
Two ultrasonic transducers per measuring path, where the two transducers both serve as transmitters and receivers,
The signal processing unit (SPU) separated from the meter body with the measurement electronics for excitation and processing of the transducer signals, the interface electronic and the display.
1 SPU (Signal Processing Unit)
2 SPU holder
3 Connection cable (for ultrasonic transducers and temperature sensor)
5 Jacketing
4 Thermal factory pre-insulation (ultrasonic transducers under the insulation)
6 Meter body
7 Meter body flange (flange)
8 Meter body neck (neck)
