Product Description
Product OverviewAs a new liquid level measurement series product, JC621R Anti-corrosive Liquid Level Transducer is specially designed for measuring sea water level and viscous & corrosive liquid level by completely using foreign state-of-the-art technology. The use of titanium alloy large flush-diaphragm sensors, advanced manufacturing and encapsulating techniques, as well as high-accuracy electronic elements has greatly enhanced service life and comprehensive performance of the product. The use of internationally state-of-the-art ceramic capacitive sensors, dry pressure measuring technology with intermediate liquid, thick-film electronic technology, surface mount technology (SMT) and PFM signal transmission technology has given full play to technical advantages of ceramic capacitive sensors, with strong corrosion, overloading and impact resistance capabilities, high stability, and quite high measuring accuracy. This series product can be extensively used in many measurement and control fields of such corrosive and viscous liquid levels as sea water level.

Dimensions
As shown in Figure 1, for installation in the water tank, water tower and other static water, generally the sensing end is directly thrown into the bottom of the water tank as far away from the pump and valve position as possible. The wiring section of the transducer is provided within the junction box, with the outgoing line pointing downward, to prevent water from penetrating into the airway tube of the air-guiding cable. Meanwhile, remember not to block the airway tube.
As shown in Figure 2, for installation in the water dam, water well and other flowing water, a steel tube with an inner diameter of approximately φ45mm is generally inserted into the water channel, where some small holes shall be drilled at the same height opposite to the water flow direction so that water can smoothly flow into the tube. The wiring section of the transducer is provided within the junction box, with the outgoing line pointing downward, to prevent water from penetrating into the airway tube of the air-guiding cable. Meanwhile, remember not to block the airway tube.
Figure 3 shows threaded or flanged connection of the split liquid level transducer in the open-hole vessel, wherein thread size or flange size are G 1 / 2 and DN20 respectively or customized.
