Remote Water Quality Monitoring

Remote water quality monitoring, one device per site: up to 11 parameters such as dissolved oxygen, pH, turbidity and chlorine, with call and SMS alarms.

Remote water quality monitoring from LoggerFlex is one LoggerFlex Data Concentrator per site that reads up to eleven water quality probes, logs every reading continuously and sends a threshold alarm to a person by push notification, email, SMS and automated phone call. The concentrator connects on its own: over cellular through a built-in eSIM, or over site WiFi, including a remote site whose internet arrives by Starlink.

One device per site, every sensor on it

Probes go in the water, one concentrator reads all of them and the readings arrive on your phone: no gateway, no PLC, no SCADA and no site IT. Every sensor is supplied with a flow cell, so the water is measured in a controlled side-stream rather than a turbulent channel, which makes today's reading comparable to last week's and puts cleaning and calibration at the wall, at working height. Volume lands on the same timestamped record from an ultrasonic water meter, DN25 (1 in.) to DN150 (6 in.), and that is what turns a concentration into a load.

Eleven parameters, one device on the wall

You run the parameters your site actually needs, not all eleven, and one concentrator reads any combination of them:

  • Dissolved oxygen: the oxygen held in solution, in mg/L
  • pH / ORP: acidity or alkalinity, plus oxidising or reducing tendency in millivolts
  • Conductivity / salinity: the total load of dissolved ions
  • Turbidity: cloudiness from light scattered by particles, in NTU
  • Suspended solids (TSS): a mass concentration of particles, in mg/L
  • Residual chlorine: the disinfectant still available at that point
  • Ammonia nitrogen: total ammonia, ammonium plus un-ionised ammonia
  • COD (chemical oxygen demand): a fast surrogate for oxidisable organic load
  • Chlorophyll / blue-green algae: algal pigment by fluorescence, not toxin
  • Oil in water: aromatic hydrocarbons by fluorescence
  • Calcium / potassium ion: one named ion, by ion-selective measurement

Cellular through a built-in eSIM, or site WiFi

The eSIM is not locked to one carrier or one country, so the same concentrator reports from a Canadian outfall or a job site in the United States, with no local SIM to source and nothing to swap when the site moves. Where there is no cellular signal at all, it joins site WiFi instead, which is how a remote site reports over a satellite link such as Starlink.

Alarms that reach a person, on four channels at once

You set the threshold for each parameter yourself, and crossing it is what sends the notice; nothing else triggers it. The breach goes out at the moment it happens to everyone on an unlimited recipient list (the on-call operator, the superintendent, the outside consultant, the owner) by push notification, email, SMS and automated phone call, because the person who has to act at 03:00 is asleep and an app badge does not wake anybody.

A continuous record, and honest limits

Every reading is timestamped and kept, with unlimited storage, trend charts and side-by-side overlays, reports, cumulative figures computed from the measured curve for event reconstruction, and CSV and Excel export. None of this replaces accredited laboratory sampling: online sensors indicate and trend continuously between samples, and the results an authority enforces on still come from an accredited lab under your own permit or bylaw. Thresholds and monitoring intervals are jurisdictional, so set your alarm to the number written in the regulation that applies to your site. A flow cell needs a pressurised line or sample pump plus a drain, the inline meter needs a full, closed pipe and is not a legal-for-trade instrument, and probes drift and foul, so servicing is real recurring work.

Where remote water quality monitoring is used

Eleven use cases show where it fits, from construction sites and small drinking water systems to farms, pools and lakes, each with the parameters that earn their place:

  • Construction stormwater, watched overnight
  • Remote and Indigenous community drinking water
  • Filters and distribution, after hours
  • Source water at the intake
  • Wells, intrusion and metered withdrawal
  • Lagoons and small wastewater plants
  • Onsite septic: instrument the treated effluent
  • Irrigation, dugouts and greenhouse fertigation
  • Pools, spas and splash pads
  • Beaches and lakes through bloom season
  • Sewer discharge points and oil separators
