ABSTRACT:
The present disclosure is directed to a fluid line pressure monitor insertable in a pipe line having a pressure side and a vent side. The monitor comprises a pair of strip members joined along their longitudinal edges and the ends of the monitor being passed over the ends of a break in the pipe line. The inside of the strip members is subjected to the pressure of the fluid being passed through the pipe and the outside of the strips being subjected to the hydrostatic pressure in a receptacle or pressure within a chamber which is pressurized from a source to be monitored. The strips may be both of an elastomeric material or a flexible metallic material or a combination of one elastomeric material and one flexible metallic material so long as the two strips are fused along their longitudinal length and fit snugly about the ends of a pipe through which a fluid flow passes from a pressure side to a vent side. The monitor is placed in a receptacle at a fixed distance above the bottom and subjected to a hydrostatic head which may vary with the fluid depth in the receptacle. Upstream of the monitor is a gauge or chart recorder which will measure the effect of the hydrostatic head in the receptacle on the monitor relative to the pressure passing through the monitor from pressure fluid passing through the pipe line.
