Planning this application?
Send the site count, signals, network, power and reporting target. We will return a hardware configuration for quotation.
Why it matters
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.
How it works
- 1A level sensor (submersible, ultrasonic or radar) measures the tank continuously.
- 2A LoRa / NB-IoT / 4G gateway sends readings from the site to the cloud.
- 3Operators see live levels and get high / low alarms by app or email.

Signals worth monitoring
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.

I/O planning checklist
Tank and liquid
Tank height, geometry, material, liquid compatibility, foam, vapor, condensation, temperature and pressure.
Measurement method
Contact or non-contact sensing, required usable range, blind zone, accuracy class and maintenance access.
Mounting
Nozzle size, sensor position, internal obstructions, cable route, stilling tube and enclosure location.
Field signals
RS485 register map, 4-20mA loop power, dry contacts, pulse inputs and any independent overflow switch.

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.
