Understanding Magnetostrictive Level Transmitters
Magnetostrictive level transmitters are cutting-edge devices that play a crucial role in accurately measuring liquid levels in petrochemical oil tanks. Unlike traditional level measurement methods, such as float and tape gauges, magnetostrictive level transmitters utilize advanced technology to provide real-time, precise data on the level of oil in storage tanks. These transmitters are equipped with a float that travels along a tube, using the principles of magnetostriction to determine the liquid level accurately.
Magnetostrictive level transmitters offer a myriad of benefits compared to traditional level measurement methods, such as enhanced accuracy, real-time data acquisition, and minimal maintenance requirements. These advantages make them the preferred choice for oil tank level detection in petrochemical facilities, contributing to improved operational efficiency and cost savings.
Problems with traditional measurement methods
In the petroleum and petrochemical refined oil circulation industry, most of the measurement of the oil content of the oil tank uses artificial climbing the tank and casting a ruler to measure. Use a metric steel tape measure with a heavy hammer or a scale with a scale to measure, manually record the reading, manually look up the table and convert it, and finally get the oil quantity data. This measurement method not only has high labor intensity, but also has unsafe factors, and cannot guarantee accuracy. In some places, capacitive / diffused silicon pressure level gauges are used for measurement. Due to the serious zero drift of this type of sensor, the measurement deviation is large, and the long-term working stability is poor, which is not welcomed by users. There are also places where isobaric membrane level gauges or mechanical float level gauges are used. However, because the membrane type liquid level gauge is greatly affected by temperature, and there is a problem of air leakage, the mechanical float liquid level gauge often appears to be stuck in the steel belt, so it has not been widely used.
How Magnetostrictive Level Transmitters Work
The structural part of the magnetostrictive liquid level sensor is composed of a stainless steel tube (rod), a magnetostrictive wire (waveguide wire), a movable float (with a permanent magnet inside), and the like.
When the sensor is operating, the circuit portion will excite a pulsed current on the waveguide wire that will generate a pulsed electromagnetic field around the waveguide wire as it propagates along the waveguide wire. A float is arranged outside the sensor rod, and the float can move up and down along the rod as the liquid level changes. There is a set of permanent magnetic rings inside the float. When the pulsed current magnetic field meets the magnetic ring magnetic field generated by the float, the magnetic field around the float changes so that the waveguide wire made of magnetostrictive material generates a torsional wave pulse at the position where the float is located. This pulse is along a fixed speed. The waveguide wire is transmitted back and detected by the detection mechanism. By measuring the time difference between the pulse current and the torsional wave, the position of the float, that is, the position of the liquid surface, can be accurately determined.
