HWLB6 magnetic float type liquid level meter is installed on the outer extension pipe of the tank, and the liquid level inside the tank can be clearly known by the duplicate indicator. A magnetic switch can also be installed on the outside of the bypass tube for electrical contact signal output, or a liquid level transmitter can be installed for long-distance liquid level signal transmission and liquid level control. A pipeline is installed on the outside of the barrel tank, and a liquid level indicator is installed outside the bypass tube. The float ball equipped with a magnet is placed into the bypass tube, because the magnetic color sheet is equipped with a magnet opposite to the magnetic field of the float ball. Therefore, when the float rises, it will attract the magnetic color sheet and flip the magnetic color sheet from white to red to indicate the actual liquid level. ● Simple design, strong, compact ● Can measure and indicate corrosive, flammable, toxic, high temperature, agitated and polluted liquid ● Flip column display, no additional power supply is required ● Corrosion resistant material, Can be used in all industrial fields ● bypass pipe and tilting column display part is completely isolated ● Design temperature range of -160℃ to 450℃ ● Suitable for medium and large tank level monitoring and pipeline pressure monitoring ● Suitable for tank, tank, pit liquid measurement. And corrosive liquids are mainly used in wastewater/water purification treatment, shipbuilding, generator equipment, petrochemical, food, electronics, dyeing and finishing, chemical, rubber and plastic, hydraulic machinery, chemical and pharmaceutical industries

The HWLB9 radar level meter antenna emits an extremely narrow electromagnetic microwave pulse, which travels in the air at the speed of light, encounters the surface of the measured medium, and some of its energy is reflected back and received by the same antenna. The time interval between transmitting and receiving pulses is proportional to the distance of the antenna to the surface of the measured medium. Due to the extremely high propagation speed of electromagnetic waves, the time interval between the transmitted pulse and the received pulse is very small (on the order of nanoseconds). The radar level meter uses a special correlation demodulation technique, which can accurately identify the time interval between the transmitted pulse and the received pulse, so as to further calculate the distance from the antenna to the surface of the measured medium. ● Small beam Angle, energy concentration, anti-interference ability, improve the measurement accuracy and reliability; Higher measurement frequency (up to 80GHZ), maximum measurement distance of 70 meters ● Not affected by the characteristics of the measured medium ● Small measurement blind area will also achieve good results for small tank measurement ● Suitable for small particle material measurement wavelength is shorter, more suitable for small particulate material level measurement, suitable for foam, Steam strong dust environment ● Low transmission power, low energy consumption, no harm to the human body pulse working mode, radar level meter low transmission power, can be installed in a variety of metal, non-metal containers, no harm to the human body and the environment ● Suitable for measuring solid particles, slurry, water, oil medium is mainly used in petroleum, chemical industry, metallurgy, food, cement, coal and other industries

The working principle of the tuning fork level switch is to vibrate the tuning fork at a constant resonance frequency through a pair of piezoelectric crystals installed on the base of the tuning fork. When the tuning fork is in contact with the measured medium. The amplitude and frequency of the tuning fork will mutate, and the intelligent circuit will detect this and convert this change into a switching signal
Strong adaptability: Different electrical parameters and density of the material to be measured do not affect the measurement.Free from maintenance: Since the detection process of the tuning fork limit switch is completed by the electronic circuit, there are no moving parts, so it does not need maintenance once it is installed and put into operation

The RF admittance level switch is composed of a sensor unit and an electronic unit. The sensor unit mainly includes three parts: measuring probe, shielding pole and grounding terminal. The height of the material is reflected as the change of admittance between the probe and the container wall. When the material reaches the switch operating point, the electronic unit reacts to drive the relay action and output the switch signal. Shielding pole can be prevented due to electrode. There is a hanging material on the wrong action signal, only when the material really reaches the setting point, the switch control signal is output.
Dielectric conductivity and temperature have little effect on capacitance. It has high anti-interference and stability
Capable of measuring highly corrosive liquid and solid particles
