Info

A dash placed on the name plate instead of pulse number, or lack of description, meansthat the appropriate pulse transmitter is not installed.The HF output is especially useful in order to control the changes of the gas flow.Pressure measurement outputs.Pressure measurement outputs (pressure pulse taps) are located on both sides of the main body(Fig. 3). The taps may be provided either with M12x1,5 thread (Fig. 6) or NPT 1/4 thread(Fig. 7). The thread type is marked on the body. The pressure taps are used for connecting thepressure transmitters directly, or indirectly by means of a three way valve. Unused taps areplugged.Fig. 6. M12x1,5 pressure measurement tap.Fig 7.

The tapsmay be provided with M14x1,5 thread (Fig.8), or NPT 1/4 thread (Fig. 9). By means oftemperature pockets electrical thermometers or temperature transmitters may be installed inthe taps. Unused taps are plugged.Fig. 8. M14x1,5 temperature measurement tap. Fig. 9. NPT 1/4 temperature measurement tap13
IV. MARKING AND LEGAL CALIBRATION (BADGING) OF THE <strong>GAS</strong> <strong>METERS</strong>Basic specification of the gas meter, serial number and production year is shown in thenameplates (Fig.10 and Fig.11). The plates are fixed to the index housing by means of screws.Two first digits of the serial number indicate the gas meter size code, according to Table 2.Information marks showing the flow direction, as well as pressure and temperature taps, areplaced on the main body (Fig. 12).Fig. 10.
