Remote monitoring for pumps and valves
Use Modulink Indi to bring compatible pressure and flow transmitters into on-site dashboards, history and alerts. Use Agri for compatible latching irrigation valves. Plan feedback and secure off-site access separately.
For water-treatment equipment and farm installations. Electrical compatibility, controls, protections and site connectivity require engineering review.
Start with the condition you need to know
A useful monitoring plan names the measurement, instrument, signal, location and operator response. “Pump on” can mean a requested command, an electrical state or confirmed water delivery. Choose the evidence your decision actually needs.
| Question | Connection to review | What the reading establishes |
|---|---|---|
| Pressure at a pump | Compatible pressure transmitter with a supported 4–20 mA signal into Indi. | Pressure at the instrument location; confirm units, range and scaling. It does not identify the cause of a change. |
| Water passing through a line | Compatible flow transmitter with a supported analog signal into Indi. | Flow where the instrument is installed. A pump command alone does not establish flow. |
| Pump or valve operating state | Review the available feedback instrument and its electrical output with engineering. | A separately measured condition. Confirm whether the application needs actual position, pressure or flow. |
| An irrigation valve command | Agri pulses a compatible DC latching solenoid; confirm the exact valve and drive requirements. | The requested action. Independent flow or position verification requires a suitable additional measurement. |
From equipment to the operator
- Identify the pressure, flow or other transmitter and review its wiring, power and output with engineering.
- Connect compatible signals to current, line-powered Indi Wi-Fi or Indi LoRa hardware. Agri uses batteries for supported soil sensors and latching-valve control.
- Send readings over site Wi-Fi or private LoRaWAN US915 to the on-site Base Station. Review received measurements, history and configured alerts there.
- For access away from the facility or farm, agree on a secure site-network connection and external notification path. A LoRa field link is not an internet connection.
Compare the exact inputs, outputs and power requirements. A sensor or terminal is not a complete remote monitoring service by itself.
Keep the existing control responsibilities explicit
Indi supports shunt-mode analog-input integration with existing PLC/SCADA instrumentation, subject to wiring review. Confirm loop loading, references and the existing indication after integration. That support does not establish universal compatibility or guarantee an installation without interruption.
Current Indi output interfaces and Agri latching-valve pulses require compatible external equipment. Agri is not a mains pump starter. Scope motor starters, interlocks, protections and control authority with the responsible site team.
Pressure and flow trends are not validated bearing-fault, vibration or predictive-maintenance diagnostics. If those are required, specify a suitable condition-monitoring system and evidence for that task.
A practical acceptance test for one installation
- Compare received readings with the instrument reference at agreed conditions and confirm units and scaling.
- Check radio coverage at the real mounting location and record what happens when readings stop arriving.
- Exercise approved commands with the site team and verify the physical result using the required feedback.
- Test on-site history and configured alerts, then test off-site access and notifications separately.
- Document who responds, how records are backed up and how power or communication recovery is handled.
Use the commissioning checklist. These are proposed site checks, not a statement that a particular installation has passed.
Evidence and cost for the decision
The Falcon Water Technologies deployment documents RO membrane-cleaning instrumentation, cycle records and read-only ERP access in Conroe, Texas, since 2025. It does not establish agricultural field outcomes, utility certification or quantified savings.
Review the catalog-backed system estimate for hardware and engineering, or the separately scoped Indi LoRa pilot and Agri pilot. Instruments, control accessories, site materials, installation and application software depend on the selected scope.
Compare the monitoring job, not just the radio
Sensaphone’s water/wastewater page describes remote-site alarms and cloud records. FarmHQ’s overview describes cellular irrigation monitoring and control. Modulink uses an on-site Base Station with Wi-Fi or LoRa field links. Match each architecture to your site, instruments, access requirements and support needs; no universal winner is implied.
