reading of the oil level it should stabilize for a few minutes. To remove or place the oil
plug you need an Allen key.
8)
Pressurize the meter with care to avoid overloading. The pressure change should never
exceed 350 mbar/sec.
9)
Connect the electrical pulsers in accordance with the connection diagram (see figure
2). The connector is in conformance with IP67 as long as the companion plug or the
protection cap is connected.
10)
An indication of the meter condition can be obtained by monitoring the pressure drop
over the meter (Pm- vs. P-point). It is recommended that the pressure drop over a new
meter is measured. This value can be compared to future measurements.
PRECAUTIONS:
1)
Never use the meter as a spool piece during welding.
2)
The meter must be depressurised before filling or adding oil.
3)
Before removing the meter, the oil should be drained.
4)
The meter should be transported and stored with the rotor axis horizontal.
5)
Use only devices with electrical characteristics as recommended (see connection
diagram figure 2)
6)
The maximum tightening torque on the Pressure and Temperature tapping connections
is: 18 Nm. To tighten the swivel nuts; use 2 wrenches to avoid over tighten and
damage the meter body.
7)
Avoid mechanical shock during handling and transportation of the meter.
8)
Avoid strong magnet fields close to the meter (particular the index), since they can
affect the metrological performance and/or interrupt the pulse generators.
9)
Seal all plugs and sight glasses to overcome fraud and/or theft of gas.
10) Lock (two bolts M5) and seal the index after adjusting it in the right position.
