When the liquid level rises or falls, the stainless steel magnetic float ball is driven to move up and down, and the float ball triggers the magnetic spring switch in the detection rod to send a signal. The measuring range is from 0 to 2.5 meters. ● Switch point can provide multi-point monitoring ● Reliable performance, good repeatability ● Long life, can be used for liquid level limit monitoring or continuous monitoring ● with normally open or normally closed output ● For corrosive media can choose different materials float ball and measuring rod ● Suitable for small and medium-sized tank level alarm, liquid level monitoring ● suitable for measuring water, Oil medium for density ≥0.55g/cm³ level measurement, mainly used in wastewater/water purification treatment, shipbuilding, generator equipment, petrochemical, food, electronics, dyeing and finishing chemistry, rubber and plastic, hydraulic machinery, chemical and pharmaceutical industries.

HWFA4 series heat flow switch adopts heat diffusion principle. There are two temperature sensors in the probe: one is used as a reference sensor to measure the temperature of the medium, and the other is used as a measurement sensor after being heated. The temperature difference between the two sensors is used as the basis for measuring the flow velocity. When the flow velocity of the medium increases, the temperature difference decreases, and vice versa. The temperature difference value is converted into standard electrical signal and displayed after processing. The HWFA4 series are all designed with all-metal shell, with 8-bit LED showing flow trend and switching status. One product is suitable for various pipe diameters. It can be set by keyboard or computer. No moving parts, maintenance-free, can be used in a variety of media.

Based on the thermal principle, the sealed probe contains two resistors, one of which is heated as the detection resistance, and the other is not heated as the reference resistance. When the medium flows, the heat on the heating resistance is taken away, the resistance value is changed, and the difference between the two resistors is used as the basis for judging the flow rate. No moving parts, maintenance-free, easy installation, one model is suitable for a variety of pipe diameter requirements, the switch-ing quantity can be adjusted continuously, very low pressure loss, compact structure, OLED display flow trend and switching state, integrated temperature measurement function, support temperature alarm and remote measurement.

HWFA2 series thermal flow switches use the propagation and diffusion characteristics of heat to transfer heat from the high temperature area to the low temperature area. Applied to flow detection, the value of regional temperature difference corresponds to the size of flow. The working principle of HWFA2 series heat transfer temperature difference is that the heat transfer module and the temperature sensing module are placed in the closed probe. The heat transfer temperature difference value of the probe is closely related to the velocity of the measured medium. When the medium in the pipeline flows at a stable velocity, the induction module receives a fixed value sensed by the heat transfer module. When the flow rate of the probe changes, the thermal module will transmit the temperature difference signal, and the corresponding flow rate will be output through the processor.
