YW801R provides field level data to controllers, PLCs and gateways. Measurement, communications and pump control are separate parts of the system.
Observe storage changes, filling operations and abnormal levels.
RS485 Modbus RTU maps measurements to supervisory points.
An external 4G gateway uploads measurements for trends and alarms.
Combine with pump controllers and level switches while keeping field protection independently configured.
Review level trends and filling operations.
Group multiple locations through gateway and platform access.

Use the transmitter for liquid-level acquisition in pools and tanks. The sensor provides measurements; selected controllers and platform architecture perform pump/valve switching and cross-site coordination.
Choose a configuration by the actual environment variables, such as temperature, humidity, gas or differential pressure. Liquid level and rain/snow detection are different sensing tasks with dedicated products.

View product detailsYW801R serves as a level point for a PLC, controller or industrial gateway using a Modbus RTU master. For multiple tanks or pools on one bus, map device addresses to physical locations and consistent units. The sensor provides level measurements while the supervisory system displays, records and interprets them for pump rooms, storage and auxiliary water management.
An external 4G gateway collects RS485 data and uploads it from pools without fixed networking or close access to an operator room. Organize live level, trends and events by tank, pump room or site. A separate controller handles pump or valve commands. This division supports an initial monitoring phase followed by alarms, operating feedback or integrated control.
The 0–3m range covers the corresponding level variation. Locate the probe with normal and maximum level and maintenance access in mind. Compare site references, sensor readings and platform readings at low, middle and high levels to check units and mapping. For level-based control, the control system organizes hysteresis, delays and low/high-level conditions alongside pump and valve operation.
An existing RS485 Modbus RTU master can acquire data locally. Add a 4G gateway or another connection when remote access is required, according to the site networking design.
Trends show filling, consumption and high/low-level changes. Combine them with pump status, pressure or flow to organize inspection, events and equipment management.
The RS485 probe uses an external 4G gateway for remote access.
It provides measurement data; a suitable controller and switching circuit operate the pump.
