Ultrasonic Gas Meter GUVR-011 A4.4
Four-path ultrasonic gas meter certified under the Measuring Instruments Directive 2014/32/EU (MID) is intended to measure, under operating conditions, the flow rate, volumetric flow and volume of the gaseous substances transported in the forward and/or reverse direction, as well as operating and down time. The meters provide measuring of the gas flow velocity in the pipe in both directions in the range from 0.1 to 40 m/c.
Depending on the flow direction, velocity has the sign “+” or “-“. The meter calculates the current volumetric flow rate as the product of the measured flow rate and the inner cross-sectional area of the pipe.
The meters allow for remote control via a computer. When using special software on the computer, at the choice of the consumer, the following data can be displayed:
- results of measurement of the direction and flow velocity, current flow rate, the volume as a cumulative sum;
- the waveform of the signal that has passed through the acoustic path;
- configuration and settings parameters of the meter;
- clock readings and calendar;
- archive data.
Functional capabilities of the meter and its setting can be changed by programming the built-in microcontroller via an external computer. To prevent unauthorized access to the meter control, the meter software is protected by a password. The password is a sequence of several numbers.
Commands of the PC operator do not change the configuration and setting of the meter or erase the archive data and are performed without password. The meter is equipped with a passive shaper of the pulse-frequency signal.
