ABSTRACT:
A filled-in-fluid and diaphragm type intermediate device for transmitting pressure and for use with a pressure, liquid level or flow rate transmitter is disclosed, which enables the measurement of the pressure, liquid level or flow rate at a high temperature by using a conventional transmitter.
This device includes a fluid-contacting flange having mounted thereon a pressure receiving element and coupled to a flange provided on the side of a fluid to be measured. A sealing flange having mounted thereon a diaphragm is provided on the side of a meter proper. A pressure transmitting pipe is coupled to the fluid-contacting flange and to the sealing flange, and contains therein a pressure-transmitting fluid which is adapted for use at a high temperature or as anti-radiant-ray fluid.
