Volume Conversion Device EK260
Elster GmbH 125
B-8 Pressure sensor
The pressure sensor can be implemented either as an inter nal or external variant.
Connection:
Pressure connection: Ermeto M12 x 1.5 male thread
Usable length approx. 10 mm
Installation information:
When connecting the pressure line to the pressure sensor, attention must be paid to the
pipe diameter to avoid damage and leaks on the gland connection. In particular the parting
point on the pipe should be checked for burrs or flaring, which cause an i ncrease in the
outside diameter of the pipe (see following drawing of the Ermeto connection on the
pressure sensor).
