NYCZ500 Magnetostrictive Liquid Level Meter Working Principle
The working principle of magnetostrictive level meter is shown in
the figure. The product mainly consists of a measuring rod, an
electronic compartment and a non-contact floating ball on the
measuring rod. The measuring rod is equipped with magnetostrictive
wire (waveguide wire), and the rod is made of non-magnetic
stainless steel tube, which protects the waveguide wire very
well.When the magnetostrictive level meter works, the pulse
generator in the electronic compartment sends out a starting pulse.
When this starting pulse is transmitted in the waveguide wire, it
generates a rotating magnetic field that advances in the direction
of the waveguide wire.This mechanical wave propagates in two
directions, the mechanical wave that reaches the end of the
measuring rod is absorbed by the damper, the mechanical wave that
travels back to the direction of the electronic bin is sensed by
the energy pickup mechanism installed in the electronic bin and
converted into a corresponding current pulse, and the energy pickup
mechanism then calculates the time difference between the two
pulses to accurately measure the height of the measured liquid
level.
NYCZ500 Magnetostrictive Liquid Level Meter Design Feature
1. Wider applicability, a variety of probe forms, a variety of
process connection forms, a variety of production materials, can be
customized design;
2. Reliability: As the magnetostrictive level meter adopts the
waveguide principle, there is no mechanical moving part, so there
is no friction, no wear. The entire converter is enclosed in a
stainless steel tube, and the measurement medium non-contact,
reliable sensor work, long life.
3. High accuracy: Since the magnetostrictive level meter works with
waveguide pulse, the measured displacement is determined by
measuring the time of the starting pulse and the ending pulse, so
the measurement accuracy is high and the resolution is better than
0.01%FS, which is difficult to achieve the accuracy with other
sensors.
4. Good safety: Magnetostrictive level meter has high
explosion-proof performance, intrinsically safe, safe to use,
especially suitable for the measurement of chemical materials and
flammable liquids. No need to open the lid of the tank when
measuring, avoiding the insecurity of manual measurement.
5. Magnetostrictive level meter is easy to install and simple to
maintain: Magnetostrictive level meter is generally installed
through the existing orifice at the top of the tank, especially
suitable for the installation of underground storage tanks and
tanks already in operation, and can not affect normal production
during the installation process.
