Tank Level Monitoring

Remote tank level monitoring for water, fuel and chemical tanks — no more manual dipping.

  1. 1. What this is for

    Read tank level remotely instead of sending someone to dip the tank.

  2. 2. Where it is used

    Water, fuel and chemical tanks at remote or unmanned sites.

  3. 3. Next step

    Send tank height, liquid type and power or network options. We return a sensor and gateway path for quotation.

How can I monitor a remote water tank with 4G?

A possible path is a level sensor with a supported RS485 / Modbus output, a compatible 4G RTU or gateway, and MQTT data sent to your cloud. Choose the sensing method and confirm the complete configuration before ordering.

Water level
Radar, ultrasonic or submersible level family

Liquid, tank height, mounting, blind zone and obstructions determine the sensing method.

Existing signal
RS485 Modbus or matching analog / pulse input

RS485 alone does not establish Modbus support. Confirm the register map or electrical input.

4G data path
Sensor → compatible RTU / gateway → MQTT-capable configuration → customer cloud

Confirm cellular bands, coverage, firmware, payload, credentials and the receiving platform.

Power
Model-specific DC supply or a sized solar / battery system

Calculate the complete sensor and modem load, reporting interval and low-sun autonomy.

Outdoor installation
Enclosure and connectors selected for the site

Confirm the exact assembly IP rating, condensation, surge protection and cable entries.

Find a starting configuration for your tank

Choose what you know. Leave the rest as “Not sure yet” and we can help with selection.

Hardware families to review

Start with the measurement and site conditions; no equipment family is selected yet.

  • Describe what you need to know about the tank; the measurement can be chosen together.
  • Compare available cellular, wired or LoRaWAN coverage before choosing the data path.

These are options for review. The exact model, compatibility, power, enclosure and certificates are confirmed before quotation.

Discuss this configuration

Your choices will appear with the inquiry. Add your email, country and a short description; a photo is optional.

Equipment selection, or help with the whole farm?

Why this application needs hardware

Tanks at remote or unmanned sites are hard to read. Without remote level data you risk dry runs, overflows and wasted truck rolls just to check a gauge.

Compare before you configure

Compare three ways to measure tank level

Select the sensing method from the liquid, tank geometry, mounting access and maintenance conditions before choosing 4G or LoRaWAN. Radar, ultrasonic and submerged pressure measurement each have different installation constraints.

Example 4G monitoring architecture, not an installation drawing. Confirm protocol, power, reporting and alarm responsibility for the selected equipment.
A

Radar

Consider non-contact measurement where access from the top is available.

Check before selection

Antenna, beam path, nozzle and internal obstructions; verify suitability for foam, condensation and the liquid characteristics against the chosen model.

B

Ultrasonic

Consider non-contact measurement with a clear acoustic path above the liquid.

Check before selection

Dead band, temperature, vapor, foam and turbulence. Check usable range in the actual tank, not only the maximum published range.

C

Submersible pressure

Consider hydrostatic measurement where a sensor can remain in the liquid.

Check before selection

Liquid density, material compatibility, vent/reference arrangement, sediment and maintenance access. Level conversion depends on density and pressure conditions.

What needs project-specific confirmation

Do not treat a remote reading as an independent overflow or dry-run protection system. Define local protection, alarm escalation and loss-of-communication behavior with the site team.

Hardware for this application

  1. 1A level sensor (submersible, ultrasonic or radar) measures the tank continuously.
  2. 2SunGene supplies RTUs, gateways, sensors and related hardware commonly used in tank level monitoring systems.
  3. 3Hardware interfaces and protocols can be selected to match the customer existing SCADA, PLC or cloud architecture.

Common measurements

Continuous level

Field input
Radar, ultrasonic or submersible transmitter via RS485 or 4-20mA
Operational purpose
Show usable volume, refill timing and level trend without a site visit.

Independent high-high level

Field input
Float, point-level switch or separate threshold output
Operational purpose
Provide an overflow alarm path that does not depend only on the continuous reading.

Low-low level

Field input
Level threshold from transmitter or point-level switch
Operational purpose
Warn before a pump loses suction or a process runs out of liquid.

Inlet / outlet flow

Field input
Pulse, 4-20mA or RS485 flow meter
Operational purpose
Explain unexpected level movement and support delivery or consumption checks.

Pump run / fault

Field input
Controller dry contacts, current status or Modbus registers
Operational purpose
Distinguish a level problem from a pump or control-panel problem.

Water-quality point

Field input
Optional pH, conductivity, turbidity or dissolved-oxygen input
Operational purpose
Add process context for wastewater or treatment sites when maintenance capacity is defined.

Alarm logic examples

High-high / overflow risk

Project logic: Continuous level or an independent point switch stays above the approved threshold for the project delay.

Operator context: Show tank ID, current level, inlet state and pump status before dispatching an operator.

Low-low / dry-run risk

Project logic: Level remains below the operating limit while an outlet pump or process demand is active.

Operator context: Check source availability, pump permissives and sensor health before restarting equipment.

Unexpected rise or fall

Project logic: Rate of change exceeds the accepted band outside a scheduled fill, drain or transfer window.

Operator context: Review inlet / outlet flow, valve state, leakage and recent maintenance activity.

FAQ

Which level sensor is suitable for an industrial tank?

Radar or ultrasonic sensing avoids liquid contact, while a submersible transmitter measures hydrostatic pressure from inside the tank. The choice depends on liquid compatibility, foam or vapor, tank geometry, mounting, blind zone, required range and site classification rather than the network technology alone.

Is LoRaWAN the level sensor?

No. LoRaWAN is the radio path. The measuring element may be radar, ultrasonic, hydrostatic or a point-level switch connected to a compatible field node. Sensor output, node inputs, regional band and payload format must be checked together.

Can one gateway monitor several tanks?

Often yes, but the answer depends on site layout, antenna height, obstructions, reporting interval, regional radio settings and whether every field node has adequate power and coverage. A site plan and pilot test are safer than assuming a fixed range.

Can wastewater tanks include water-quality monitoring?

Optional pH, conductivity, turbidity or dissolved-oxygen points can be added when the process need, calibration routine, cleaning access and maintenance ownership are clear. These instruments should not be treated as maintenance-free accessories.

What does SunGene need before quoting tank monitoring hardware?

Provide the tank and liquid details, photos, measured points, alarm requirements, field power, site network, country, target platform, quantity and schedule. Exact model, material compatibility, certification and enclosure are confirmed before order.
