More Hot Water Metering at The Healing Place
In this video I show how we set up a non-invasive flow meter on another hot water line at The Healing Place of Wake County as part of our design process for a solar hot water system. The flow meter requires a straight run of pipe in order to properly collect data. In addition to the meter, we connect our datalogger to record the flow data for several days. This gives us a realistic profile of the kitchen’s hot water demand. Once our measurements are complete, we’ll compare them to data from the other water heater feeding the kitchen area. Stay tuned!

What is the brand and model of the metering devise you use, and what is the cost of the system with the USB option?
I have been integrating the Grundfos VFS into the piping with a controller and couple of temperature sensors to measure both the flow and incoming and outgoing temperature for Btu measurements.
Dennis,
We have been using Badger 200 series flow meters with Badger 3050 monitors. The monitor reads the flow sensor and two temp sensors and calculates the Btu production. The monitor has a LCD display that can show total Btu, Btu/hr, and the temps. Options on the monitor include USB and RS455 outputs. You can check their website for details.
The Badger meter series is heavy duty commercial. They have been around for over 100 years.
The Grundfos system should be fine for small residential jobs. I don’t know if they have larger sizes. Europe is way ahead of us in providing solar thermal residential products.
