(One) Working principle and function of UHC type Magnetic
double-color Level Indicator uses magnetic floater as sensible
component,and show liquid location and interface through
interacting of magnetic object between magnetic floaters and show
color column. UHC type Magnetic double-color Level Indicator
applies communicating tubes working principle to guarantee the
equal level between the measured object and the measuring tube. It
display the digit of the liquid level location when color column
overturn that dues to interacting of magnetic object between
magnetic floater and displayed color plunger which cause the equal
changing of the measured object and the measuring tube, White for
air and red for water. Magnetic double-color Level Indicator of
local display has the characteristics of direct display,
eye-striking, having high speed, high accuracy, easy operation and
wide view angle, tight and reasonable structure. It is safe and
reliable and has no phenomenon of liquid running out, bubbling,
dripping and leaking”, and less maintaining, low maintaining cost.
Furthermore, its indicating functions needn’t use electric supply
separately, so if there is something wrong with the supplying of
electricity ,it won’t influence display of digital showing .If
matched with UR electric resisting transducer or UB electric
resisting and electric current transmitter and(secondary) digital
display instrument ,so can realize electric remote transmission,
and output nominal power supply of 4-20mA(or 0-10mA). On that basis
we have imported technology HART to satisfy the need of field bus
(mixture of imitation and digit). HART adopt FSK technology
coordinate with industrial control computer internet.
In order to adapt to different working environment , our Magnetic
double-color Level Indicators have produced more than 20 different
types of meter, such as side mounted, buried tank top mounted,
thermal type ( steam insulating sheath, electric thermal insulation
) , type of specially used by boiler, antisepsis type
(glass fiber reinforced plastic, ABS, UPVC,
TA2 ) to satisfy customers.
