Junction Box
Shown as Figure 1, the sensing end is directly thrown on the bottom of the water tank when installed on in the static water in the water tank and water tower, as far as possible away from the pump and valve position. The wiring circuit of the transducer is provided within the junction box, with downward outgoing wire, to prevent water from penetrating into the air–leading tube of the air–leading cable. Meanwhile, never clog the air–leading tube.
Shown as Figure 2, a steel tube with φ45mm inner diameter approximately is inserted into the water channel when installed in the flowing water in the water dam and well. Open some small hole on the reversing water flow direction so that water can smoothly into the tube. The wiring circuit of the transducer is provided within the junction box, with downward outgoing wire, to prevent water from penetrating into the air–leading tube of the air–leading cable. Meanwhile, never clog the air–leading tube.
Shown as Figure 3, a split liquid level transducer is threads or flanges connected in the open–hole vessel, of which thread size is G 1 / 2 and of which flange size is DN20 or customized.

Split type: The section of the sensor throwing into the liquid is of fullysealed stainless steel structure, of which enclosure for the electronic wiring circuit is cast aluminum structure for purpose of alignment and adjustment of wiring connection.Integrated type: Both the sensor and the amplified circuit are provided in the fully sealed enclosure madeof stainless steel, without external alignment and adjustment.The enclosure of the sensor is designed with IP68 and the junction box is designed with IP65.This product takes the high performance pressure sensor as the measuring element, with high accuracy, small dimensions, easy operation, strong disturbance immunity, high reliability, good stability, high sensitivity, waterproof, and dewing resistance. It is of free maintenance, easy installation and commissioning. It is directly thrown into the water to measure the liquid level from the transducer end to the liquid surface.Special Throwing - in Water Level Transmitter MS321A
