DDTOP UHC Magnetic Level Gauge

UHC magnetic level gauge provides a safer, more reliable and more visible option than conventional glass level gauge. The float moves up and down with the change of level, and the float transmits the level signal through the coupling magnetic field, which divides into the local indication type and the remote transmission output type.
Chamber and float have a variety of materials and pressure-grade options and are suitable for complex process applications of current major operating devices.

 Description of DDTOP UHC

UHC magnetic level gauge is a new generation of level meter based on the magnetic coupling principle. This product has advanced technology, reasonable structure, clear and intuitive display. It is suitable for petroleum, chemical, electric power, light industry, pharmaceutical and other industries. The level gauge is divided into side-mounted type and top-mounted type. Side-mounted type is for side-mounted applications. Top-mounted type for top-mounted applications, particularly suitable for level measurement in underground storage vessels.

Working Principle

UHC magnetic level gauge is mainly composed of measuring tube and local indicator. Side-mounted type level gauge is connected to the process vessel through interface flanges to form a connector. The float in the measuring tube moves up and down with the liquid level (or interface) changes. The magnetic steel in the float drives the local indicator, which clearly and intuitively indicates the liquid level (interface level) in the process vessel. Top-mounted type level gauge directly installed on the top of the process vessel. The float moves up and down with the liquid level (or interface) to drive the magnetic connecting rod to move up and down. The magnetic steel in the magnetic connecting rod drives the local indicator, which clearly and intuitively indicates the liquid level (or interface level) in the process vessel. If used in conjunction with remote transmitter and upper and lower limit alarms, it can easily realize remote transmission and automatic control of liquid level signals.

Features

1.The float adopts 304,316 L, TA2 and TC4 material. It has good temperature resistance and can reach to 450℃.

2.The welding process meets the requirements of PED welding process. The chamber is made of 304,316 L. The maximum pressure can reach to 26 MPa.

3.Local indicator type and remote output type with level alarm are optional.

4.According to customer requirements, through a variety of production types, the products can be applied to a variety of working conditions.

3. Transmitter Part

There are two types of level transmitters: Hall-Resistive level transmitter and magnetostrictive level transmitter.

3.1 Hall-resistive level transmitter

The transmission device is tied to the outside of measuring tube. When the float moves up and down with liquid level, the hall switch corresponding to the liquid level value is turned on by the magnetic field of the float, which changes the resistance value and current, and is converted into a 4-20 mA signal through the conversion circuit to achieve the purpose of transmission.

  • Measuring range:200mm~6000mm(can be produced out of range)
  • Power supply:24 VDC
  • Output:4~20mA with HART
  • Ambient temperature:-40℃~+80℃
  • Medium temperature:-40℃≤T≤+250℃(When T≥120℃,the transmission part is not allowed to keep warm)
  • Accuracy:±10mm
  • Cable Entry:M20×1.5(female thread)or as customer requirement
  • Explosion-proof type:Explosion-proof:Ex db II C T4…T6 Gb

Intrinsic safety:Ex ia II C T5…T6 Ga

  • Ingress protection:IP66

3.2 Magnetostrictive Level Transmitter

The transmission device is tied to the outside of measuring tube, and there is a magnetostrictive wire in the remote transmission tube. A microprocessor-controlled sensor circuit emits current pulses along the magnetostriction, creating a circular magnetic field around the magnetostriction line. The magnetic steel inside the float magnetizes the magnetostrictive line along the axial direction. The superposition of the two magnetic fields generates a torsional pulse that travels along the magnetostrictive line to the top of the sensor, and the pulse transmission time is captured and calculated by the circuit unit to determine the float position. and is converted into a 4-20 mA signal through the conversion circuit to achieve the purpose of transmission.
