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 showing 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 type of meter, such as side mounted, buried tank top mounted, thermal type ( steam insulating sheath, electric thermal insulation ) , type of special used by boiler, antisepsis type(glass fiber reinforced plastic, ABS, UPVC, TA2 ) to satisfy customers.
