Wireless Submersible Level Sensor with Display Head
Model: WCLL300 series display head wireless
Features:
1. Local display on the head
2. Fully wireless, no construction required
3. Ultra-low power, long battery life
4. Multi-mode wireless remote transmission
5. High-accuracy, reliable measurement
| Product Introduction
Independently developed by winchen sensor, the WCLL300 series display-head wireless submersible level sensor / level gauge is an intelligent level instrument integrating high-accuracy hydrostatic level measurement, on-site LCD display head, wireless remote transmission and battery power. The sensor body uses a fully sealed 316L stainless steel structure. Once placed in the liquid, it allows both intuitive on-site reading of the level value and scheduled transmission of data to the cloud or a user-specified platform via the built-in 4G or LoRa wireless link. The entire unit operates entirely on a built-in high-energy lithium battery, requiring no external power supply or signal cable. This fundamentally solves the difficulty of level monitoring in remote, mobile or hard-to-wire locations, making it widely suitable for remote level management of water utilities, hydrology, agriculture and industrial storage tanks.
| Features
1. Local display on the head: a high-definition LCD digital display head can cycle through the real-time level value, battery level, signal strength and more, so on-site inspections can read data without any tools;
2. Fully wireless, no construction required: battery power + wireless communication eliminates the laying of power and signal cables; ready to use once installed, greatly reducing installation costs, especially suitable for renovation of old pools and deep wells in the countryside;
3. Ultra-low power, long battery life: uses a micro-power processor and intelligent sleep algorithm with a built-in large-capacity lithium battery; based on a normal collection cycle, the battery life can reach 3~5 years;
4. Multi-mode wireless remote transmission: supports 4G/LoRa and other wireless transmission protocols, with wide signal coverage and strong penetration; data can be transmitted directly to a cloud platform or connected to the user's own system;
5. High-accuracy, reliable measurement: selected diffused silicon pressure core with overall accuracy of 0.5%FS and built-in temperature compensation; level measurement is unaffected by ambient temperature fluctuations and offers good repeatability;
6. Sturdy, durable and fully sealed: an integrated stainless steel probe with a high-strength polyurethane or PTFE breathable cable; IP68 high protection, resistant to slurry, weak acids and alkalis and humid environments, stable in long-term immersion;
7. Intelligent early warning with active push: high and low level alarm thresholds can be flexibly set via the cloud platform; once exceeded, alerts are immediately pushed to managers by SMS and other means to prevent overflow or drying up;
