Abstract
The invention discloses a non-plug-in type multi-parameter pipe network on-line monitor which comprises a flow pipe and a meter head arranged on the flow pipe. The outer wall of the flow pipe is provided with a pressure detection module, a pressure drawing hole enabling the flow pipe to be communicated with the pressure detection module, an ultrasonic transducer and a blind hole. A temperature sensor chip is arranged in the blind hole. By the adoption of the non-plug-in type multi-parameter pipe network on-line monitor, the pressure, flow and temperature of fluid in the flow pipe can be measured at the same time, and multiple parameters of the fluid are monitored on line. All transmission wires are stored in a concentrated mode, thereby being cleaner, neater and more normative.
