Technical Field
The utility model belongs to the technical field of the level gauge, concretely relates to measuring device of liquid level in storage tank.
Background
In the field of chemical enterprises, the index of liquid level measurement is generally used, and the liquid level measurement devices on the market at present probably have the following types: the device comprises a measuring device based on the reflection distance of radar waves or ultrasonic waves, namely a radar or ultrasonic liquid level meter; the second is based on measuring equipment with the same height of the floater and the liquid level, namely a floating ball liquid level meter; thirdly, a liquid level measuring device utilizing a radioactive source, and fourthly, a pressure type liquid level measuring device based on the Pascal law, namely a pressure or differential pressure type liquid level meter. Various measuring devices have certain limitations: the radar liquid level gauge fails as soon as the steam is large; the ultrasonic liquid level meter has limited measuring distance and also fails under the condition of large steam; the floating ball liquid level meter is easy to be blocked when the medium is easy to scar; the radioactive source liquid level meter is high in price, higher in required safety protection level and has certain potential safety hazard; the pressure type liquid level meter is usually installed by opening a pressure guide hole at the bottom of a groove, additionally installing a primary valve, and then installing a diaphragm box or connecting a pressure guide pipe with a transmitter.
SUMMERY OF THE UTILITY MODEL
To the problem among the prior art, the utility model provides a can accurate measurement steam great and easily scab measuring device of liquid level in the storage tank of medium liquid level.
The utility model adopts the following technical scheme:
the device for measuring the liquid level in the storage tank is characterized by comprising a pressure transmitter (1), an upright post (2), a diaphragm capsule type pressure sensor (3) and a capillary tube (5), wherein the upright post (2) is arranged at the top of the storage tank, and the pressure transmitter (1) is arranged on the upright post (2); the pressure transmitter (1) is connected with the diaphragm capsule type pressure sensor (3) through a lifting rope (4), and the diaphragm capsule type pressure sensor (3) is placed in the storage tank; one end of the capillary tube (5) is connected with the diaphragm capsule type pressure sensor (3), and the other end of the capillary tube (5) is connected with the pressure transmitter (1).
The device for measuring the liquid level in the storage tank is characterized in that the lifting rope (4) is connected with the diaphragm capsule type pressure sensor (3) through a U-shaped bolt and a nut matched with the U-shaped bolt; the pressure transmitter (1) is arranged on the upright post (2) through a U-shaped bolt and a nut matched with the U-shaped bolt.
