Submersible Level Transmitter product overview

Submersible Level Transmitter

The Submersible Level Transmitter is a highly reliable liquid level measurement instrument designed for continuous monitoring of liquid depth in tanks, wells, and reservoirs. It operates on the proven hydrostatic pressure measurement principle, ensuring accurate and dependable readings for a wide range of industrial and environmental applications.

By measuring the static pressure exerted by the liquid column, this level sensor directly calculates the liquid level height, making it an essential tool for process control and inventory management.

Core Advantages & Working Principle

Hydrostatic Pressure Measurement Principle

The core working principle of this submersible level sensor is based on the fundamental physics of hydrostatic pressure. When the sensor is submerged in the measured liquid, the pressure (P) on its liquid-facing diaphragm is defined by the formula P = ρgh + Po, where ρ is the liquid density, g is gravitational acceleration, h is the liquid level height, and Po is atmospheric pressure.

A key feature is the integrated venting device, which introduces atmospheric pressure into the sensor's negative pressure chamber. This ingenious design allows the transmitter to measure only the pressure component ρgh, directly yielding the precise liquid level depth, independent of atmospheric pressure changes.

What is RTU Remote Terminal Unit? How does RTU work in water monitoring systems?
View Answer
<p><strong>RTU (Remote Terminal Unit)</strong> is a microprocessor-controlled electronic device that serves as the critical interface between physical field equipment and centralized SCADA (Supervisory Control and Data Acquisition) or telemetry systems. In water monitoring systems, an RTU collects real-time data from field sensors—including flow meters, pressure transmitters, water level gauges, and water quality analyzers—and transmits this information to a central control center via wireless or wired communication networks.</p> <p><strong>How RTU Works in Water Monitoring Systems:</strong></p> <ul> <li><strong>Data Acquisition</strong>: The RTU continuously polls connected sensors through multiple I/O interfaces including analog inputs (4–20mA, 0–10V), digital inputs (pulse, status), and serial communication ports (RS-232/RS-485). For water monitoring, typical sensor inputs include flow rate from electromagnetic or ultrasonic flowmeters, water level from radar or submersible level sensors, pressure from transmitters, and water quality parameters such as pH, turbidity, and dissolved oxygen.</li> <li><strong>Signal Processing & Logging</strong>: Raw sensor signals are filtered, linearized, and converted to engineering units. The RTU performs local data logging with time-stamped records stored in non-volatile memory, ensuring zero data loss during communication outages. Typical storage capacity supports 10,000+ records with configurable logging intervals from 1 second to 24 hours.</li> <li><strong>Communication & Telemetry</strong>: RTUs support multiple communication protocols and transport layers. At the field level, <strong>Modbus RTU</strong> (over RS-485) is the most widely adopted protocol for sensor integration, while <strong>Modbus TCP</strong> enables Ethernet-based networking. For long-range telemetry, modern RTUs integrate multi-mode wireless options including <strong>4G LTE, NB-IoT, LoRa/LoRaWAN</strong>, and satellite communication, allowing deployments in remote watersheds, mountain reservoirs, and underground monitoring wells where traditional wired infrastructure is unavailable.</li> <li><strong>Control & Automation</strong>: Beyond data collection, RTUs execute local control logic—triggering alarms when water levels exceed thresholds, automatically starting or stopping pumps based on tank levels, controlling valve positions for flow regulation, and implementing PID control loops for pressure management in water distribution networks.</li> <li><strong>Power Management</strong>: For remote sites without grid power, RTUs feature ultra-low-power designs with sleep-mode current consumption as low as 50μA, enabling months of autonomous operation on battery power supplemented by small solar panels (typically 10–50W). Advanced power scheduling wakes the RTU on configurable intervals or upon sensor-triggered events.</li> </ul> <p><strong>RTU vs PLC — Key Differences:</strong></p> <p>While both RTUs and PLCs (Programmable Logic Controllers) perform industrial control functions, they are optimized for different deployment scenarios. RTUs are purpose-built for <strong>geographically distributed, remote, and environmentally harsh installations</strong> with emphasis on wide-area communication, ultra-low power consumption, and extended temperature ranges (-40°C to +70°C). PLCs excel in <strong>centralized factory-floor automation</strong> with high-speed deterministic control, extensive I/O density, and complex sequential logic. In water monitoring, RTUs are the preferred choice for river basin telemetry networks, reservoir monitoring stations, irrigation canal gate control, and urban drainage monitoring—applications where sites may be tens or hundreds of kilometers apart with limited power and no permanent communication infrastructure.</p> <p><strong>Typical Deployment Architecture:</strong></p> <p>A typical RTU-based water monitoring system follows a three-tier architecture. At the <strong>field layer</strong>, sensors (flowmeters, level gauges, rain gauges, water quality probes) connect to the RTU via wired interfaces within a monitoring station enclosure. The RTU aggregates and pre-processes data locally. At the <strong>communication layer</strong>, data is transmitted via 4G/NB-IoT/LoRa to a central data server or cloud IoT platform using protocols such as MQTT, HTTP, or the hydrological standard <strong>SL651-2014 / SZY206</strong>. At the <strong>application layer</strong>, SCADA software, water resource management platforms, and mobile dashboards visualize real-time and historical data, generate reports, and issue alarms—enabling water authorities to make informed operational decisions.</p> <p><strong>Ecolor Technology RTU Solutions:</strong></p> <p>Ecolor Technology's <strong>Hero V9 Series</strong> offers two primary RTU configurations for water monitoring applications:</p> <ul> <li><strong><a href="/EN/products/hero-v9-ec32-measurement-control-terminal">EC32 — Measurement and Control Terminal</a></strong>: A versatile industrial RTU with rich I/O interfaces, Modbus RTU/TCP support, 4G/LoRa/NB-IoT communication, and ultra-low-power design suitable for general water resource monitoring, pump station control, and irrigation automation. Features local data storage, remote firmware upgrade, and wide operating temperature range.</li> <li><strong><a href="/EN/products/hero-v9-ec60-data-acquisition-terminal">EC60 — Compact Data Acquisition Terminal</a></strong>: A cost-optimized, compact RTU designed for high-density sensor deployments with streamlined I/O, embedded 4G communication, and simplified installation—ideal for large-scale river monitoring networks and smart city drainage monitoring projects where cost per monitoring point is critical.</li> </ul> <p>Both models feature solar-ready power input, IP65+ environmental protection, and compatibility with Ecolor's cloud-based water monitoring platform for seamless data integration and visualization.</p>
