Wider Applicability Magnetostrictive Liquid Level Meter Strong Reliability Industrial Applicatons
Excellent Safety Magnetostrictive Liquid Level Meter Easy To Install And Maintain Operating Principle
As showing picture, magnetostrictive liquid level meter is formed
from a measuring rod, an electronic chamber and a non-contact
floating ball sleeved on the measuring rod.
Magnetostrictive wire (guided wave wire) is installed in the
measuring rod. The measuring rod is made of non-magnetic stainless
steel tube, which protects the guided wave wire. When the
instrument is working, the pulse generator in the electronic
chamber sends out a starting pulse which transmits through the
wire, it generates a rotating magnetic field moving. When this
magnetic field meets the permanent magnetic field in the float
ball, it generates a magnetostrictive stretching effect, causing
the guided wave wire to twist and generate a constant speed
mechanical wave which transmits in two directions. The mechanical
wave reaching the end of the measuring rod is absorbed by the
damper. The mechanical wave transmitting back to the electronic
chamber is sensed by the energy pickup device installed in the
electronic chamber, and then converted into the corresponding
current pulse. The energy pickup device calculates the time
difference between the two pulses to give an accurate measurement
of liquid level.
Magnetostrictive Liquid Level Meter Design Feature
◎ Wider applicability, with a variety of probe forms, process
connection forms, and production materials, which can be
customized.
◎ Strong reliability: since the magnetostrictive liquid level gauge
adopts the waveguide principle. The whole converter is enclosed in
a stainless steel tube, which is non-contact with the measuring
medium. The sensor works reliably and has a long service life.
◎ High precision: because magnetostrictive liquid level gauge works
with waveguide pulse, the measured displacement is determined by
measuring the time of the starting pulse and the ending pulse
during the work, so the measurement accuracy is high, and the
resolution is better than 0.01% FS, which is an accuracy that is
difficult to achieve with other sensors.
◎ Excellent safety: the magnetostrictive liquid level gauge has
high explosion-proof performance, is intrinsically safe and safe to
use, and is especially suitable for the measurement of chemical raw
materials and flammable liquids. It is unnecessary to open the tank
cover during measurement to avoid the insecurity of manual
measurement.
◎ The magnetostrictive level gauge is easy to install and maintain:
the magnetostrictive level gauge is generally installed through the
existing pipe orifice on the tank top, especially suitable for the
installation of underground storage tanks and storage tanks that
have been put into operation, and can not affect the normal
production during the installation process.
