• How much water is in the water well?
  • What’s the depth of the reservoir, impoundment pond, or other water body?
  • Is it flooding? You or your organization need to send flood alerts when water levels go above your custom threshold?

We’ll help you answer these questions and any others you have on water monitoring!

Here’s a simple step-by-step video tutorial on how to remotely monitor water levels and depths using pressure transducer sensors. In the video above you’ll learn how to use Valarm Tools Cloud with sensors hubs (e.g., GSM 3G or WiFi) and water sensors.

If you need to monitor water, have a look at this customized webpage dashboard we made for customers who need to monitor water wells, water levels, and water usage with flow meters.

To use Valarm Tools Cloud software like in this video, you can get all the hardware you need at shop.valarm.net.

Howdy! This is Edward from Valarm.

In this video you’ll learn how to easily and rapidly deploy remote water monitoring units.

This demo tutorial breaks down water levels or depths sensors, a.k.a. pressure transducers, that our customers use for Industrial IoT applications like the water well you see in the picture here. Our customers use Valarm to monitor water well depths as well as flow meters so they can remotely monitor real-time water usage. The rugged Valarm units deployed in the field use the same technology as the hands on demo in this video. Next we’ll be breaking down the key components for water monitoring with Valarm.

These are the key pieces you need to monitor water depths. You’ll put them into a weatherproof box and provide a source for power and internet.

– This is a pressure transducer or water level sensor. These sensors are made by companies all around the world. Flowline and In-Situ are examples of a few brands our customers like to use. The pressure transducers send a raw 4-20mA analog signal that we’ll convert to a real world depth measure like feet.

– This is a 4-20mA sensor adapter that converts the raw analog 4-20mA signal from the sensor to a digital reading. This sensor adapter is available at http://shop.valarm.net.

– This is a sensor hub that receives data from connected sensors, like the 4-20mA sensor here. The GSM sensor hub or WiFi sensor hub then sends the data to Valarm Tools Cloud ( http://tools.valarm.net ) via GSM mobile cell network, WiFi, or ethernet. You can get your sensor hubs and sensors from http://shop.valarm.net.

Watch our other videos for step-by-step instructions on how to connect your sensor hubs to your http://tools.valarm.net account, if you haven’t already done that.

Now that everything’s plugged in we can deploy the pressure transducer in the water well or other body of water. You can configure your sensor hubs to automatically upload the water sensor data to Valarm Tools Cloud as often as you’d like. Based on the pressure of the water above it, the sensor sends data that you can use know water levels and depths. We’ll change the depth of the sensor so you can see the water levels changing on http://tools.valarm.net.

Next you’ll logon to http://tools.valarm.net to see your water monitoring information. In the Valarm Tools Cloud Device Manager click your device. Here you’ll see all of your latest historical sensor information from sensors connected to this sensor hub. There are regular sensor reports from the sensor hub with 4-20 mA sensor readings from the pressure transducer. In the graph you can see a sample of the data where the water sensor was rising and falling into the water.

Note that these are raw 4-20mA values and we want to know real world measurements like feet or meters. To do that we’ll set up a Linear Scaler under Configure Data Path. Here you see the configuration we’ll use with this water level sensor where we’ll convert the raw 4-20mA values to depths in feet. Provide a name and info for your linear scaler and select where the inputs and outputs are coming from. In this case we’re using channel 1 of the 4-20mA sensor adapter and we’ll output the result in feet to the Calc 1 field. Next set the min and max raw values that your sensor can report, in this case 4 and 20. Then the maximum output values. A reading of 4mA for this sensor is 0 feet of water depth and a reading of 20mA for this sensor is 2 meters or 6.5616 feet of water. Click save to finish your linear scaler setup.

Now when you see the Calc 1 these values correspond to water depths in feet like you see in this graph of the water sensor information we gathered earlier in the pool. All of your sensor data and fields are available throughout Valarm Tools Cloud like in the Esri ArcGIS maps you see here. Click any of your sensor hub’s locations to the latest information on your maps.

You can use our JSON APIs to send your real-time, GPS-tagged sensor information to a web-based dashboard. We can help make your organization a custom web dashboard for any sensors you’re monitoring. Send us a message, let us know what you need, and we’ll figure out how we can best help you!
