The AT35-3-U6 electrode-type level sensor is designed specifically for level-signal acquisition in hot-water tanks and delivers excellent performance when used with BESFUL water-level controllers.

The MK-20 water-level transmitter works with BESFUL C- and D-series products to continuously detect ten water levels (10%, 20%, 30% ... 100%).The transmitter host has a built-in digital display of the current measured water level (%). Users can view the tank's water volume directly on site near the tank, even when far from the control box, greatly facilitating installation, commissioning, and routine maintenance. The compact main unit can be mounted directly outdoors with a rainproof cover.

The AT35-7-U6 electrode-type water-level sensor is made of SUS316# stainless steel, and its electrode surface reliably detects and transmits signals indicating its position in the water.

The AT35-1-U6 single-pin water-level sensor cable is made of 316 stainless steel with UL-certified wire. Its electrode surface reliably detects and transmits signals indicating its position in the water.

M29 is a dedicated water-level and temperature adapter board for use with our products with 50X70-series cutouts, including KT4, BF-3030, BF-450T, and BF-8805A. The M29 junction box converts the four-level resistance signals detected by the AT35-7-U6 water-level electrode into a two-wire resistance signal for connection to a water-level gauge.

M40 is an accessory for BESFUL controllers BF-DKT4, BF-M170G, and BF-170MW. After the multi-pin probe cable immersed in the tank is connected through the M40, it becomes a two-core signal cable that connects to the controller's water-level terminals. (Built-in resistor network with a total resistance of 60K, compatible with the water-level resistance networks of most solar controllers on the market.）
