Measurement device

A device configured for determining a pressure of liquid within a pipe, the device comprising:

• a first probe;
• a second probe;
• and
• a control unit, wherein the control unit is configured to execute an application program to perform a method of determining the pressure of liquid within the pipe, the method comprising:
• transmitting, by the first probe, ultrasound, wherein the first probe is disposed on a surface of the pipe;
• receiving, by the second probe, the transmitted ultrasound, the second probe being disposed on a surface of the pipe opposite to the first probe;
• determining a thickness of the pipe at a surface on which the first probe or the second probe is disposed, wherein the pipe thickness at the surface on which the first probe is disposed is determined using ultrasound transmitted by the first probe, or wherein the pipe thickness at the surface on which the second probe is disposed is determined using ultrasound transmitted by the second probe;
• determining a celerity of the transmitted ultrasound through the liquid within the pipe based on the determined pipe thickness;
• determining the pressure of the liquid based on the determined celerity of the transmitted ultrasound,
• wherein the device further comprises a frame configured to be coupled to the pipe, wherein the first probe and the second probe are disposed on the frame;
• and
• a track disposed on the frame, wherein one of the first probe and the second probe is disposed on the track such that the first probe or the second probe is movable along the track,
• wherein, when the frame is disposed on the pipe, the first probe and the second probe are longitudinally offset along the pipe such that the second probe is located at an angle relative to the first probe, and
• wherein the probe disposed on the track is movable so that the second probe is disposed on the surface of the pipe opposite to the first probe.
