DG-RAS-R-S20L10 Radar Ultrasonic Flow Meter

The product employs a combined sensing approach using a hydrostatic pressure sensor and a conductivity sensor to monitor water levels. The hydrostatic pressure sensor primarily measures the height of standing water, while the conductivity sensor detects the electrical conductivity of the water and determines whether the water has reached an “immersed” state, thereby achieving equilibrium with atmospheric pressure.

产品描述

- Commodity name: DG-RAS-R-S20L10 Radar Ultrasonic Flow Meter
Measurement principle

The product employs a combined sensing approach using a hydrostatic pressure sensor and a conductivity sensor to monitor water levels. The hydrostatic pressure sensor primarily measures the height of standing water, while the conductivity sensor detects the electrical conductivity of the water and determines whether the area is “submerged,” thereby achieving equilibrium with atmospheric pressure. Powered by an integrated battery, this sensor offers long‑term operational endurance and includes a built-in wireless transmission module, enabling convenient real-time data delivery to meet remote monitoring requirements.

Application scenarios

The product is suitable for water‑logging detection in a variety of settings: in underground spaces, it can be deployed in utility tunnels for power and telecommunications; in transportation infrastructure, it supports water‑logging monitoring at subway stations and similar areas; in road‑side facilities, it enables water‑level detection around electrical equipment such as switches, transformers, and control cabinets; additionally, it can be used to monitor water accumulation near solar‑energy systems, wind turbines, and other similar installations.

When used in conjunction with a dedicated control host, this sensor enables intelligent management of water‑accumulation conditions. The sensor employs wireless RF transmission to send water‑level monitoring data to the controller; upon receiving the RF signal, the controller executes pre‑programmed control algorithms to automatically operate the relevant water‑removal equipment. Additionally, the controller can transmit real‑time data—such as water‑level readings and system status—via 4G wireless or RS‑485 communication to a server, facilitating remote centralized management and analysis.
