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.

Key Features

Measurement parameters: water level, electrical conductivity, temperature, signal strength

Overall measurement range: 0–2 meters

Stainless steel pit-type enclosure

Ultrasonic, pressure (optional), and conductivity multi‑mode composite sensor

Annular pressure‑transmission method (when a pressure module is optionally selected)

Built-in integrated dedicated antenna

Easy battery replacement and reduced O&M costs.

Compact in size, designed for underground installation, and does not detract from the urban landscape.

Supports remote OTA

All parameters support remote configuration.

Equipped with sediment penetration detection capability

Equipped with the Ping An Reporting feature.

Supports wake-up via air gesture technology.

Application scenarios

Measurement and early warning of water accumulation on municipal roads, park pathways, and critical infrastructure (such as transformers and other electrical facilities, pumping stations, and substations). For water‑level monitoring in flash‑flood channels, a pressure sensor is required; additionally, an integrated algorithm for estimating flow based on the Manning equation can be optionally configured to derive discharge data, thereby providing comprehensive and accurate information to support flash‑flood monitoring and early warning.
