Problems solved by technology

Its disadvantages are as follows: firstly, the pressure-taking port, temperature-measuring port, pressure sensor, temperature sensor, explosion-proof head, explosion-proof casing, cables, etc. are installed outside the flowmeter casing, not only the components are easily aging and damaged, but also easily damaged Others are damaged, bringing many unsafe factors to users, which is a headache for users and gas management departments; the second is because of pressure-taking ports, temperature-measuring ports, pressure sensors, temperature sensors, explosion-proof heads, explosion-proof casings, cables, etc. Installed outside the flowmeter housing

Example Embodiment

[0011] Example 1: Refer to the attached figure 1 with figure 2 . figure 1 with figure 2 Involved is the gas waist wheel flowmeter. The flowmeter includes a fixedly connected flowmeter body 2, a flowmeter partition 3, a flowmeter end cover 4 and a flowmeter cover 9, except for the magnetic induction flow signal recorded in the existing patented technology (01253920.1) on the side of the flowmeter end cover In addition to the output mechanism 6, two channels 11 with O-ring 12 sealing ports are arranged in their appropriate positions, and a threaded sealing port is arranged at the other end of the channel 11, and pressure sensors (or pressure transmitters) 5 are installed respectively. And temperature sensor (or temperature transmitter) 8, the flow signal, pressure signal and temperature signal are respectively transmitted by the wire 7 in the flow cover directly to the microcomputer digital display 10 connected with the cover 9 (also can be designed For the signal to be transmit...

Example Embodiment

[0013] Example 2: Refer to the attached image 3 . Built-in gas flowmeter, the background technology is gas waist wheel flowmeter or gas turbine flowmeter. The body is equipped with temperature sensor 8, pressure signal transmission air film port 13, pressure signal sampling port 14 and matching with pressure signal sampling port The pressure sensor 5, the signal transmission line 7 of the pressure sensor and the temperature sensor are located in the body and directly conveyed to the digital display 10 communicating with the body. The pressure of the gas medium acts on the pressure transmission gas film port 13, the force deformation of the gas film on the gas film port directly acts on the incompressible oil, and the oil acts on the sensor located at the pressure sensor sampling port to achieve the purpose of pressure sampling. .

Example Embodiment

[0014] Example 3: Refer to the attached Figure 4 . Mainly used in gas turbines and other gas flow meters. The pressure, temperature sensor (transmitter) and flow sensor in embodiment 1 are installed in the cover 9 outside the wall of the 2 channel of the flowmeter body, and the flow sensor receives the flow signal from the impeller or other flow signaling mechanism At the same time, the pressure and temperature sensors measure the pressure and temperature of the fluid to achieve the same purpose as in Example 1.

Abstract

A built-in gas flowmeter has the sensors for acquiring the temp compensation signal and pressure compensation signal, and the both signals are transmitted to digital display. Its advantages are good protection to its parts and effective electromagnetic fielding.

Description

Technical field: [0001] The invention relates to a gas flowmeter, in particular to a gas waist wheel flowmeter and a gas turbine flowmeter, and belongs to the field of gas flowmeter manufacturing. Background technique: [0002] It is well known that the density of all gases, including natural gas and city gas, will change with the change of its pressure and temperature. According to this physical characteristic, in order to accurately measure the flow through the pipeline, especially for the measurement of trade settlement, and to protect the interests of both consumers and producers, it is necessary to measure the temperature of the medium while measuring the flow value And the pressure value, through calculation to get the real flow value of the medium flowing through the pipeline - "standard condition flow", referred to as standard condition flow. Although the gas waist wheel flowmeters and gas turbine flowmeters currently on the market have realized the "standard state ...
