Abstract

The invention provides a split type combined parameter instrument. The split type combined parameter instrument comprises an instrument head assembly; a combined sensor, wherein the upper end of the combined sensor is connected with the lower end of the gauge outfit assembly, a pressure sensor, a micro differential pressure sensor, a temperature signal line and a signal conversion circuit are arranged in the combined sensor, a tubular first split connector is arranged at the lower end of the combined sensor, and two differential pressure signal input channels and a temperature signal input line plug are arranged in the first split connector; a three-valve group, wherein a tubular second split connector is arranged at the upper end of the three-valve group; the second split connector is used for being detachably connected with the first split connector, and a differential pressure signal output channel used for being connected with the differential pressure signal input channel and a temperature signal line socket used for being connected with the temperature signal input line plug are arranged in the second split connector; and a Pitot tube probe which is installed at the lower endof the three-valve set through a probe protection tube and a sealing fastener, and a temperature sensor is arranged on the Pitot tube probe.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a split-type combined parameter instrument. Background technique [0002] At present, when monitoring the flow of gas pipelines and discharge pipes, the installation methods of various flow meters are mostly to cut off a section of the pipeline, and weld flanges at the front and rear cutoffs, so that multiple bolts can be used to test the meter during installation. The main body is fastened. The flow meter adopting the above-mentioned installation method is not convenient for installation and maintenance. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a split-type combined parameter instrument, which is simple and convenient to install and maintain, has many functions, compact structure, small volume and low cost. [0004] The technical scheme that the present invention adopts is as follows: [...
