SFL200 series float level switch is mainly composed of three parts: magnetic float, sensor and transmitter. 304 stainless steel, PVC, PTFE and other materials are used as protection pipes and installation fixings for the floating ball liquid level meter; for highly corrosive media, polytetrafluoroethylene is sintered on the surface of contact medium metal protection pipes and floating balls

SFLS300 series side mounted floating ball liquid level switch is based on the liquid buoyancy principle. When the floating ball moves up and down due to the buoyancy, the magnetic spring switch in the junction box is affected by the arm end magnet, and the "no" and "NC" contacts are exchanged. The same principle is applied to the microswitch device. The magnet in front of the microswitch.

SLS3220 NB IOT water level gauge (IOT water level monitoring terminal) is an intelligent product with water level detection, data acquisition, Nb IOT wireless communication, battery self power supply and other functions. It can be widely used in groundwater observation logging, water pool, drainage inspection well, river, cable trench and other places for remote monitoring of water level.

All welded structure. Non-contact measurement. High stability, long life. High temperature resistant medium.

SUL809 Ultrasonic liquid level meter can adopt two-wire system, three wire system or four wire system technology. The two-wire system is: the power supply and signal output circuit are shared; the three-wire system is: the power supply circuit and signal output circuit are independent. When the DC 24 V power supply is used, a 3-core cable can be used, and the negative end of power supply and signal output share a core wire; the four wire system is: when AC 220 V power supply is used, or when the AC 220 V power supply is used, or when the signal output circuit is used, the ultrasonic liquid level meter can be used When the power supply circuit is required to be completely isolated from the signal output circuit, a 4-core cable should be used. DC or AC power supply, with 4 ~ 20mADC, high and low switch output.

The high frequency radar level meter antenna emits a very narrow microwave pulse, which propagates in space at the speed of light. When it encounters the surface of the measured medium, part of its energy is reflected back and received by the same antenna. The time interval between transmitting and receiving pulses is directly proportional to the distance between the antenna and the surface of the measured medium. Because the propagation speed of electromagnetic wave is very high, the time interval between the transmitted pulse and the received pulse is very small (nanosecond level), which is difficult to confirm. The level meter of 26G HF radar adopts a special correlation solution technology, which can accurately identify the time interval between the transmitted pulse and the received pulse, and further calculate the distance between the antenna and the surface of the measured medium.

The SRL900 laser radar level gauge adopts the laser measurement method to measure the material level without contact, and is not affected by the viscosity corrosion of the material. The protection grade reaches IP67 and can be used in a humid environment. The host has an LCD to visually display the liquid level. Observing the position, with a man-machine interface is more convenient to set up, this product has the function of distinguishing the agitator, and can be used very reliably in the working conditions of the reactor crystallizer.

The structural part of the magnetostrictive liquid level sensor is composed of a stainless steel tube (a measuring rod), a magnetostrictive wire (waveguide wire), a movable float (with a permanent magnet inside), and the like. When the sensor is operating, the circuit portion will excite a pulsed current on the waveguide wire that will generate a pulsed electromagnetic field around the waveguide wire as it propagates along the waveguide wire.

The SFL600 series oil volume sensor is based on the principle of radio frequency capacitance measurement and adopts a unique technology to realize automatic calibration. It is not affected by temperature and medium changes, and has high measurement accuracy and strong anti-interference ability. This technology fills the domestic gap and is at the international leading level. It can be installed in various occasions to accurately measure the oil level of gasoline, diesel, hydraulic oil and other weakly corrosive liquids.
