Need to effectively manage water resources?

How do you rapidly deploy water monitoring devices?

Watch the video here to learn how to do it in less than 4 minutes. Quickly and cost-effectively connect your water flow meters to to monitor water usage and add telemetry to your fluids!

You’re about to see how ridiculously easy it is to monitor water usage and water flow meters. Here you see an Industrial IoT solution for remotely monitoring this water flow meter.

You’ll be using a PWM or pulse-width modulation sensor adapter to count the pulses or ticks from the flow meter. The PWM sensor adapter connects to your sensor hub, which connects to Valarm Tools Cloud via GSM 3G 2G GPRS, WiFi, or ethernet. This EKM water flow meter outputs 1 pulse per tenth of a cubic foot. So each tick we count is approximately .75 or three quarters of a gallon of fluid. We’ll remember this when we’re looking at the pulse counts on Valarm Tools Cloud.

Make sure your water flow meter is properly connected to your PWM sensor adapter. The ground, which is the black cable here, is connected to the ground connector on the PWM sensor adapter. The sensor output, which is the red wire on this flow meter, is connected to the sensor and pull-up connector on the PWM sensor adapter.

That’s it! Let’s turn on the faucet and water the pool while monitoring our water usage with the flow meter. When you’re ready to deploy, just put everything into a weatherproof box and provide power via solar, mains, or whichever power source works best for your scenario.

Now we’ll look at the water sensor data on If you haven’t already linked your sensor hub to, then check out our other videos and tutorials to connect your sensor hub and sensors to

On you see the PWM sensor data from the water flow meter. Since the PWM sensor adapter is in edge count mode, we’ll divide the PWM counts by 2 to get flow meter pulses, then multiply that by the amount of water per pulse. You can set up a totalizer to keep a running total sum of water usage in the exact format you want it, like gallons or liters. Here’s an example of how to set up a totalizer for this flow meter model where each pulse is approximately .75 or three-quarters of a gallon. See and our write-up on Valarm Tools totalizers for more on setting up totalizers and all of your totalizing options.

Now that the water telemetry data is on you can view it on maps, graphs, and use our APIs to integrate all of your Industrial IoT information into a real-time web dashboard like the one you see here. This web dashboard uses the PWM sensor adapter you saw in this video to monitoring water usage counting pulses from McCrometer water flowmeters. Each water well at this California golf course is monitored by Valarm. In addition to the water flow meter at each water well, a pressure transducer or water level sensor, like those made by In-Situ, is connected to a 4-20mA sensor adapter to monitor water depths in the water wells.
