ACL-Z level meter
Brief introduction:
ACL-Z series wireless magnetostrictive level meter is high-tech intelligent level meter that we research and develop according to the requirements of industrial field, and we adopt the technology of sensor signal processing, mathematical modeling, information operation and intelligent communication technology accumulation. This gauge adopts the magnetoctrictive theory and has the advantages of high precision, long linear range and absolute position measurement, which can measure the tank liquid level accurately. It also has the advantages of high precision, strong environment adaptability, high reliability, simple installation, convenient maintenance. Wireless communication integrated the two most popular industrial wireless communication mode: ZigBee, WirelessHART, adopted the advanced and perfect software management technology, micro power consumption device with data alarm, emergency, instrument faults, such as battery alarm priority mechanism, ensure the data real-time state monitoring and instrumentation, built-in high-capacity high-performance lithium batteries. Realize the remote real-time monitoring, wireless transmission, no need site wiring, saves on the ordinary instrument field wiring required, save the manpower and construction cost. This level meter is widely used in petroleum, chemical, food, medicine, and other areas of the level measurement, and gradually replaces the other traditional liquid level meter; it has been the first choice of the liquid level measuring instrument.

When ACL-Z series wireless magnetostrictive level meter sensor works, the sensor circuit part will inspire a pulse current on the wire waveguide, when this current diffuses along the waveguide, it will produce the impulse current magnetic field around the waveguide. Magnetostrictive theory, namely: strain pulse produced when different magnetic fields intersect, the detected time can calculate the accurate position of intersection. There is a float equipped outside sensor rod, this float can move up and down along with the change of the level. There is a group of permanent magnetic ring inside the float. When the impulse current magnetic field meet the circular magnetic field produced by float, the magnetic field around the float will change, so as to make the waveguide wire made of magnetostrictive materials produce a torsion wave pulse in float position, this pulse will be returned along the waveguide at a fixed speed and detected by the detection institution. By measuring the time lag between the pulse electric current and torsion wave, we can know the float location that is liquid height. Magnetostrictive liquidometer technology advantage: magnetostrictive liquid level meter is suitable for high precision requirement of clean liquid level measurement, precision can reach 1 mm, the latest product precision can reach 0.1 mm.
