Abstract
The invention discloses an external non-contact measurement barrel type ultrasonic liquid level meter comprising a measurement barrel (2), a measurement sensor (3), a calibration sensor (4) and a meter body (5). An upper communication tube (8) and a lower communication tube (9) are arranged on the upper portion and the lower portion of the measurement barrel (2), a bypass tube (10) penetrating the lower communication tube (9) is arranged below the measurement barrel (2), the measurement sensor (3) is mounted at the bottom of the measurement barrel (2), the calibration sensor (4) is mounted at the bottom of the bypass tube (10), and the measurement sensor (3) and the calibration sensor (4) are respectively connected with the meter body (5) via signal lines. The external non-contact measurement barrel type ultrasonic liquid level meter is simple in structure, convenient to mount, accurate in measurement, stable in a long term and convenient for a user to adjust meter parameters in an HART (highway addressable remote transducer) communication mode, and is long in service life as the meter body is mounted outside a container and in indirect contact with liquid media, and blockage or corrosion of the sensors due to the liquid media in the container is avoided.
Description
Technical field
The present invention relates to liquid level gauge, be specifically related to a kind of outside non-cpntact measurement formula ultrasonic level gage.
Background technology
To the height (to call liquid level in the following text) of liquid in container when measuring, most ofly adopt two kinds to measure liquid level gauges.A kind of is the internal measurement liquid level gauge, the influence that this liquid level gauge often causes survey sensor often to be stopped up or be corroded and be subjected to factors such as High Temperature High Pressure by the liquid medium in the container, survey sensor needed for repair and replacement just must be opened container and take out sensor, but for the restriction of factors such as production and safety, container can not at will be opened; Another kind is externally measured liquid level gauge, and this measurement liquid level gauge must directly contact the influence that can cause liquid level gauge to be stopped up or corrode and be subjected to factors such as High Temperature High Pressure by liquid medium equally with liquid medium in the container in the perforate mode.
Summary of the invention
The objective of the invention is to: a kind of outside non-cpntact measurement cartridge type ultrasonic level gage is provided, and liquid level gauge directly contacts with the liquid medium in the container is non-, guarantees the long-time stable, accurate of level gauging.
Technical solution of the present invention is: this liquid level gauge comprises measures tube, survey sensor, calibrating sensors and meter body, measure the upper and lower of tube and establish communicating pipe and lower communicating tube respectively, measure the below of tube and establish the other pipe that connects lower communicating tube, the bottom of measuring tube installs and measures sensor, the bottom installation calibrating sensor of other pipe, survey sensor, calibrating sensors connect meter body through signal wire respectively.
During installation, last communicating pipe and the lower communicating tube of measuring tube are communicated with on tank body through flange, stop valve respectively.
The present invention has the following advantages: 1, meter body is installed in outside the container, directly contacts with liquid medium is non-, avoids the liquid in container medium to obstruction or the corrosion of sensor and is subjected to the influence of factors such as High Temperature High Pressure, increases the service life; 2, simple in structure, easy for installation, measure accurately long-term stability; 3, HART communication modes makes things convenient for the user to adjust the instrument parameter.
Description of drawings
Fig. 1 is mounting structure synoptic diagram of the present invention.
Among the figure: 1 tank body, 2 measure tube, 3 survey sensors, 4 calibrating sensors, 5 meter body, 6 flanges, 7 stop valves, 8 last communicating pipes, 9 lower communicating tubes, 10 other pipes.
Embodiment
As shown in Figure 1, this liquid level gauge comprises measures tube 2, survey sensor 3, calibrating sensors 4 and meter body 5, measure the upper and lower of tube 2 and establish communicating pipe 8 and lower communicating tube 9 respectively, measure the below of tube 2 and establish the other pipe 10 that connects lower communicating tube 9, the bottom of measuring tube 2 installs and measures sensor 3, the bottom installation calibrating sensor 4 of other pipe 10, survey sensor 3, calibrating sensors 4 connect meter body 5 through signal wire respectively.
During installation, last communicating pipe 8 and the lower communicating tube 9 of measuring tube 2 are communicated with on tank body 1 through flange 6, stop valve 7 respectively.
Claims (1)
1. outside non-cpntact measurement cartridge type ultrasonic level gage, it is characterized in that: this liquid level gauge comprises measures tube (2), survey sensor (3), calibrating sensors (4) and meter body (5), measure the upper and lower of tube (2) and establish communicating pipe (8) and lower communicating tube (9) respectively, measure the below of tube (2) and establish the other pipe (10) that connects lower communicating tube (9), the bottom of measuring tube (2) installs and measures sensor (3), the bottom installation calibrating sensor (4) of other pipe (10), survey sensor (3), calibrating sensors (4) connects meter body (5) through signal wire respectively.
