Shell + Inductive Diaphragm: 316 stainless steel
Sealing Components: Nitrile rubber (NBR), suitable for clean water and mild sewage
Cable Configuration: Standard = Range + 2 meters (This model comes with a total cable length of 5 meters, and can be extended for customization)
Connection Method: Two-wire system (black wire for power +, red wire for signal output)
Certification: CE compliance
III. Measurement Principle
The liquid static pressure is proportional to the liquid level height. The diaphragm at the bottom of the probe is subjected to water pressure, and the built-in diffusion silicon pressure core converts the pressure into a standard 4-20mA current signal, which is directly connected to PLC, digital display meters, DCS systems for converting water level height.
IV. Main Applications
1. Water Supply and Drainage Waterworks (Main scenarios)
Continuous monitoring of water level in water tanks, filter tanks, reservoirs in waterworks
Level measurement and control of regulating tanks, biochemical tanks, collection wells in sewage plants
Automatic start-stop control of groundwater wells, pump room water tanks
2. Building HVAC
Monitoring of liquid levels in central air conditioning water tanks, expansion water tanks, collection pits, alarm for water shortage and overflow prevention.
3. Municipal Pipelines
Water level monitoring in underground utility tunnels, rainwater wells, flood storage tanks, collection of water level data for remote water management systems
4. Industrial Tanks
Continuous measurement of liquid levels in water purification equipment, pure water tanks, environmental water treatment tanks, to achieve automatic water replenishment and upper/lower limit interlock alarms.
5. Ancillary Systems
Directly connected to PLC, RTU, paperless recorders, level controllers to complete water level collection + automatic pump control.
