Investing in an automated groundwater well telemetry station compliant with Decree 53/2024/ND-CP and Circular 17/2021/TT-BTNMT is a mandatory legal obligation for all manufacturing enterprises, industrial parks, and clean water utilities extracting groundwater at 10 m³/day-night or greater. To optimize capital expenditure (CAPEX) while ensuring 100% smooth inspection and regulatory acceptance by the provincial Department of Natural Resources and Environment (DONRE), business owners and project managers require transparent, granular cost models.
This technical guide is part of DeviceLab's comprehensive engineering handbook on automated groundwater and surface water monitoring.
In the market today, installation pricing quotes for a single groundwater well telemetry station vary wildly—ranging from 45,000,000 VND to over 130,000,000 VND depending on sensor origins, datalogger architecture, and contractor markup. Many enterprises fall into the trap of purchasing cheap, fragmented DIY assemblies (hobbyist microcontrollers, unisolated converters, low-grade 4G routers) only to face chronic data corruption, fried electronics from seasonal lightning, and heavy administrative penalties from environmental inspectors. This comprehensive guide provides an itemized cost breakdown across four key equipment categories, transparent turnkey package estimates, and a technical evaluation of why the DeviceLab DL-ENV10 Datalogger delivers the lowest Total Cost of Ownership (TCO).
Key Investment Factors for Groundwater Telemetry (Decree 53/2024/ND-CP):
- Estimated Total Investment: 45,000,000 VND to 115,000,000 VND per well station (depending on pipe diameter and borehole depth).
- Primary Cost Drivers: Electromagnetic flow meter line size (DN50 to DN250), borehole depth for submersible sensor cable (50m to 150m), and industrial datalogger compliance.
- Mandatory Inspection Deliverables: Complete measurement calibration certificates, transmission logs transmitting text files to DONRE FTP/SFTP server, and official acceptance dossiers.
- All-In-One Solution: DeviceLab DL-ENV10 consolidating power management, multi-bus telemetry, 128MB local ring buffer, and direct FTP transmission into 01 compact DIN-rail unit.

4 Primary Equipment Categories Constituting Telemetry Station Costs
A compliant groundwater well telemetry system comprises four essential components:
1.1. Central Telemetry Cabinet & DeviceLab DL-ENV10 Datalogger
The central telemetry cabinet serves as the operational brain of the station. This category includes:
- Industrial outdoor IP65/IP66 enclosure with polyester electrostatic powder coating.
- DeviceLab DL-ENV10 Datalogger with integrated 4G LTE modem and dual isolated RS485 communication ports.
- DIN-rail 24VDC 60W industrial power supply with battery backup UPS circuit.
- Multi-stage Type 2+3 surge protection devices (SPD) protecting AC power and RS485/analog signal lines.
- Estimated Cost: 18,000,000 – 28,000,000 VND.
1.2. Submersible Hydrostatic Level Sensor & Borehole Cable
To measure static and dynamic water levels compliant with Circular 17, the sensor must withstand continuous submersion in mineralized groundwater:
- SUS316L stainless steel sensor probe with piezoresistive ceramic or silicon diaphragm.
- Polyurethane (PUR) shielded borehole cable with internal atmospheric capillary vent tube.
- Vented junction box with replaceable silica desiccant cartridge.
- Estimated Cost: 7,000,000 – 16,000,000 VND (proportional to cable length: 50m, 80m, 120m, or 150m).
1.3. Electromagnetic Induction Flow Meter (Magmeter)
To record instantaneous abstraction rates ($m³/h$) and cumulative totals ($m³$):
- Industrial electromagnetic flow converter and sensor body with PTFE / Hard Rubber lining and Hastelloy-C electrodes.
- RS485 Modbus RTU communication output.
- Estimated Cost: 12,000,000 – 45,000,000 VND depending on pipe size (DN50, DN80, DN100, DN150, or DN200) and brand tier (Asian vs European manufacture).
1.4. Field Installation Labor, Calibration & DONRE Commissioning
Hardware alone is insufficient without certified engineering execution:
- Mechanical pipe fitting, flange welding, and sensor guide conduit installation.
- Electrical wiring, grounding resistance testing ($R < 4 Omega$).
- Metrological verification stamping and calibration certificates from accredited testing centers.
- DONRE transmission protocol integration, test run documentation, and final handover dossier.
- Estimated Cost: 8,000,000 – 18,000,000 VND.

Why DIY Assemblies (PLC + HMI + 4G Router) End Up Costing More
Many contractors attempt to assemble monitoring cabinets using cheap programmable logic controllers (PLCs), consumer touchscreens (HMIs), and commercial 4G office routers to reduce initial quotes. However, field experience across hundreds of industrial installations shows that DIY assemblies invariably lead to higher lifetime costs:
- High Idle Power Consumption: A PLC + HMI + Router combination consumes $25W–45W$, rendering battery backup bulky, expensive, and unable to sustain more than 2 hours of power outage. The DL-ENV10 consumes less than $1.5W$.
- Lack of Local Flash Ring Buffering: Commercial routers lack non-volatile text buffering algorithms. When cellular 4G signals drop during thunderstorms, transmission fails and data is lost forever, resulting in regulatory breach citations.
- Software Licensing & Inflexible Maintenance: When provincial DONRE servers update encryption certificates or change FTP directory structures, proprietary PLC systems require expensive software engineers to re-program ladder logic on site. The DL-ENV10 allows instant remote firmware and configuration updates over the cloud.
