产品描述

- Commodity name: DG-PLM-R-L5 Hydrostatic Level Transmitter
Measurement principle

The product employs hydrostatic and water‑immersion (conductivity) sensors to measure water level. It supports multiple power supply options, including external power and a self‑powered mode (the standard model, which is also recommended for self‑powering). It can transmit acquired water level data or elevation data to a server via a reliable 4G wireless connection.

The product’s housing is made of stainless steel, offering a robust and durable structure that can withstand a wide range of challenging operating environments. Additionally, it features an IP68 waterproof rating, ensuring stable and reliable performance even under harsh conditions. This electronic water level sensor accurately measures changes in water levels, enabling users to remotely monitor water levels at any time and providing an efficient, dependable solution for water level monitoring in municipal, transportation, water resources, and hydrological applications.

Supports wake-up via air.
Three structural configurations: integrated floor-standing, integrated wall-mounted, and split wall-mounted.
Built-in automatic atmospheric pressure self-balancing algorithm
Protection rating: IP68

Application scenarios

Waterlogging measurement and early warning for municipal roads, park pathways, critical above‑ground electrical and power infrastructure (such as transformers, substations, and other power facilities), urban EV charging stations, and subway facilities. Particularly suited for use in urban underpass tunnels and hydrological settings.

Technical Specifications

Water level accuracy: 0.2% FS ± 0.002 m (resolution: 0.001 m)
Measurement range: 1 meter (standard), 2 meters, custom options (e.g., 0.4 m, 0.8 m)
Sensor: Static pressure type + Electrical conductivity
Configuration: Integrated base-mounted, integrated wall-mounted, and split wall-mounted (with replaceable battery)
Battery-powered version: Built-in lithium‑thionyl chloride battery, non‑rechargeable, 76 Ah / 3.6 V DC, with self‑discharge not exceeding 5% per year.
Battery‑type endurance: 4G: 5 years (recommended), NB‑IoT: 5 years (measured and reported every five minutes)
External power supply: 12 VDC; solar power or grid‑connected 12 VDC; no battery‑life concerns; optional wired RS‑485 output.
Wireless breakpoint resumption: When the base station signal is interrupted, data is automatically saved and, once the wireless signal is restored, the timestamped data is resent.
