Mobile testing device for a stationary pressure-measurement device links to a gas pipe with a reference pressure device

摘要

A testing device has reference pressure measurement devices (3a,3b) to be connected to a gas pipe and parallel to a stationary pressure measurement device. Linked to the reference pressure measurement device, a modem connects to an evaluatory unit with a programmable data store, in which measurement values are corrected, evaluated or compared to set-point values.
