SISCO digital capacitive water level transmitter enables automatic water level detection without direct contact with the liquid. It supports NPN and PNP outputs, operates on 12-24VDC power, and is compatible with various non-metallic pipes such as PVC, glass, and PE. The capacitive water level sensor is ideal for automatic water level monitoring applications.
Core Detection & Performance Advantages
- Stable Capacitive Sensing Principle: Our digital capacitive level sensor gauges liquid level shifts based on capacitance changes. Non-invasive outer pipe wall mounting eliminates pipe drilling and precisely monitors fluid conditions inside pipelines.
- Accurate Adjustable Calibration: The onboard digital display panel works with a potentiometer knob to adjust sensitivity across multiple levels. Real-time numeric readings let technicians set detection thresholds accurately and efficiently.
Structural Material & Practical Durability
- Heavy-Duty Protective Housing: Solid casing structure resists collision and abrasion, greatly prolonging service life under severe industrial surroundings.
- High-Flexibility Connection Cable: Premium raw materials endow the wire with powerful tensile capacity. The cable withstands repeated bending without cracking, maintaining reliable wiring connection for long-term continuous work.
- Intuitive Human-Machine Operation: Capacitive water level sensor combined with a digital screen and status indicator delivers clear running feedback, simplifying field commissioning, parameter modification, and routine fault diagnosis.
Applications
Our digital capacitive water level transmitter fits various working conditions with powerful versatility. It mainly supports automatic control of water pumps, water tower water level management and intelligent water level sensing for electronic toilets, covering all devices needing pipeline liquid level feedback.

Wiring Diagram
Q1: What type of pipes are compatible with the digital capacitive water level sensor?
A1: The digital capacitive water level sensors are commonly compatible with non-metallic pipes, including PVC, glass, ceramic, acrylic, rubber, and PE. Metal pipes may affect capacitance detection and require different sensing solutions.
Q2: What output signal does the digital capacitive water level sensor provide?
A2: Digital capacitive water level sensor provides NPN and PNP output signals, allowing flexible connection with different control systems such as PLCs, controllers, and automatic water management equipment. The dual output design improves compatibility with various industrial control circuits.
Q3: Does this digital capacitive water level transmitter need to touch the water?
A3: No, this digital capacitive water level transmitter does not need to touch the water when using non-contact capacitive detection technology. The capacitive water level transmitter can be installed outside compatible non-metallic pipes or containers and detects water level changes by measuring capacitance variations through materials such as PVC, glass, acrylic, ceramic, rubber, and PE. This non-contact design helps prevent contamination, reduce maintenance, and simplify installation in water monitoring systems.
Tips: How to select the appropriate range for a digital capacitive water level sensor?
To select the appropriate range for a digital capacitive water level sensor, consider the pipe size, material, wall thickness, and required detection position. Choose a sensor range that matches the outer diameter and thickness of the non-metallic pipe or container to ensure stable sensing performance.Â
It is also important to check the liquid type, installation environment, and detection requirements. A suitable sensing range helps achieve reliable water level detection while avoiding false signals caused by unsuitable pipe materials or excessive wall thickness. For accurate selection, confirm the sensor's detection range specifications and compatibility with the application before installation.
