BluCloud - Remote Cellular Liquid Level Monitoring

The Challenge

Remote sites are expensive to check on.

Wells, tanks, and reservoirs are often miles from the nearest network or power line. Knowing their level usually means sending someone to look.

Truck rolls for every reading

Drive time, labor, and fuel — multiplied by every site you add.

No infrastructure on site

No WiFi, no wired network, often no power. Traditional telemetry needs all three.

Data that's already stale

Standalone loggers hold data until someone downloads it — long after it was useful.

Problems found too late

Overflows and dry wells surface on the next visit instead of when they start.

How It Works

From the bottom of the well to your inbox.

A BluCloud unit powers your sensor, logs and transmits readings over cellular, and delivers them to a cloud platform that alerts you the moment something needs attention.

Drop it in

Lower the probe to depth and route the cable to the unit above grade — or wire in an instrument you already own. Installation takes minutes.

It connects itself

The unit registers to the strongest available network. Tap it three times to send a test reading before you leave site.

View data & get alerts

Check live levels on the dashboard, tune thresholds remotely, and get notified the moment something needs attention.

The Device

A single sealed unit. Nothing else required.

Sensor interface, cellular modem, and a long-life battery in one weatherproof enclosure. No separate gateway to wire up, no WiFi network to configure.

Field-replaceable battery — 3–5+ year target life, no depot return
Never loses data — SD card backup syncs when coverage returns
Status at a glance — diagnostic LEDs visible through the clear lid
Rugged — IP65 polycarbonate, UL-certified NEMA 4X enclosure
Remotely managed — OTA firmware updates and configuration

Where do you fit?

One platform, three ways to work with BluCloud.

I need to monitor my sites

Utilities, farms, operators, and facilities that need level and sensor data from remote wells, tanks, and reservoirs.

I sell instruments or equipment

Distributors and wholesalers: add cellular monitoring to the sensors and instruments your customers already buy.

I'm building a product

OEMs and integrators: build on BluCloud's cellular hardware, connectivity, and cloud instead of building the stack yourself.

Cloud Platform · Included

Every device, one dashboard.

A web platform included with every BluCloud device — nothing to install on site.

Live status — latest reading, last check-in, battery, and signal
Alert automation — rules per device or fleet, routed to email, SMS, Slack, or webhook
Custom calibration — convert raw readings to feet, inches, gallons, or % full
Site map & history — GPS location and a full reading log
Unlimited devices — one site or an entire fleet

Connectivity

Connects wherever there's a signal.

One embedded, multi-carrier SIM attaches to the strongest available network at each site — and re-selects if conditions change. No SIM swaps and no carrier contracts to manage.

Verizon, T-Mobile & AT&T — all major US carriers

Frequently asked questions

Does BluCloud need WiFi or a gateway?

No. Every BluCloud unit has its own cellular modem and connects directly over LTE-M / NB-IoT using a multi-carrier SIM that selects the strongest available network. There is no WiFi to configure and no gateway to install.

How long does the battery last?

The target battery life is 3–5+ years at standard check-in intervals, using the default 9,000 mAh field-replaceable battery. Actual life depends on how often you sample and report and on signal strength. External DC / solar power is also supported.

Can I use my own sensor?

Yes. The Cellular Monitoring Unit and Industrial Sensor Gateway accept any compatible 0–5 V or 4–20 mA sensor, so you can add cellular reporting to instruments you already own. MODBUS RTU / RS-485 support is coming soon.

Where does it work?

BluCloud units use a multi-carrier SIM with access to 550+ networks in 190+ countries, including Verizon, T-Mobile and AT&T in the United States. Coverage depends on the plan you choose (US, Canada, Global, or Custom).

How do I get alerts?

Create alert rules in the dashboard for a single device or your whole fleet, and route them to email, SMS, Slack or a webhook. Each rule keeps a delivery log so you can see what fired and when.

What happens if a site loses coverage?

The unit keeps logging readings to its on-board SD card and syncs them when cellular service returns, so gaps in coverage don't mean gaps in data.

Where is it made, and is it warrantied?

BluCloud units are designed and manufactured in the United States and carry a 1-year warranty.

Stop guessing. Start knowing.
