Thermometer application in oil field

For multiphase medium level of the container, according to adopt a set of temperature time, due to take over must also stretch up and down into the different medium, Dh and Dh 'are not equal to zero, and can't accurately display level.

need to display liquid level in the three-phase separator for crude oil (commonly Or light oil) And water, and so many set two sets of thermometer were used, respectively, according to crude oil ( Or light oil) And water level.

should be paid attention to in the installation of the thermometer and position: n5U magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

( 1) The bottom of the crude oil thermometer to take over should be higher than the highest level of water. , the liquid level of crude oil shows that the key to keep the thermometer, single properties of the medium in which 2 g = g1, so just make sure the lower takeover above the water level, can reliably show container liquid level of crude oil.

( 2) A thermometer to take over the top of the water should be less than the minimum control the liquid level of crude oil. Magnetic flap water thermometer thermometer mainly used to display the container of the oil-water interface, can be seen from the above analysis, to accurately show the container of the oil-water interface, must make a thermometer in the crude oil level remained stable. When the container liquid level of crude oil is higher than the upper port of the thermometer, equivalent to Dh1 = 0, so DH '= 0. Considering generally has a thermometer display blind area, so a thermometer to take over the top of the water should be less than the minimum control oil level around 200 mm. And the operation of the water level is generally not higher than a thermometer to take over the top of the water. Setup method USES a single set of thermometer can be seen from the above theoretical analysis, a single set of thermometer is not accurately show that two kinds of liquid level, because the two port thermometer design makes the same density of the liquid cannot be connected. With the method of group level, while it is possible to eliminate the three-phase liquid level display error, but the opening is more, the installation more troublesome, and increase the manufacture cost.

in addition, can by improving the way of the thermometer, realize the correct display of the two phase medium. Method is to use three ports of thermometer, i. e. , on the basis of the original two port thermometer, add a to take over the side, the installation location is located in the lowest level of crude oil and water between the highest level, to achieve the goal of medium connected. But the effect still need to practice test. N5U magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
