SunEarth VFS 10‑200 NPT Flow & Temperature Sensor
SunEarth VFS 10‑200 NPT Flow & Temperature Sensor is backordered and will ship as soon as it is back in stock.
The VFS 10-200 NPT Flow & Temperature Sensor is offered for liquid-flow and temperature monitoring in solar thermal and compatible hydronic systems. The Grundfos VFS 10-200 base sensor combines both measurements using vortex-shedding technology.
The base sensor measures 10–200 L/min (approximately 2.6–52.8 US GPM) and 32–212 °F (0–100 °C). It uses a composite housing and provides analog ratiometric voltage outputs to compatible control equipment.
Key Features
- Two Measurements in One Sensor: Monitors liquid flow and temperature using the Grundfos VFS platform.
- Wide Flow Range: Measures 10–200 L/min, approximately 2.6–52.8 US GPM.
- Vortex Measurement: Uses vortex shedding without moving measuring parts.
- Analog Signals: Separate ratiometric voltage signals report flow and temperature.
- Composite Construction: The manufacturer identifies composite housing and flow-pipe materials.
- Solar Monitoring Applications: Provides measurements for a compatible controller or monitoring system.

The mini ultra boiler i purchased was built very strong and worked great after being installed.
Price was right
This is a great unit for anyone who is on a well!!
Great pump and great price. I actually ordered from a human being and they were great
Very nice expansion tank. Mine is a 16 gallon. Has feet so it will sit on the floor next to your boiler and doesn’t have to be mounted on the wall.
It’s sturdy enough to support your Air Separator, Pressure Regulator and Backflow Preventer.
I recently installed my new 29kw BTH Ultra boiler and so far I am really impressed.
We live in an old 2 story brick farmhouse built in 1814! This unit replaced an Outdoor Wood Boiler with a 750 gallon tank. It was about 30 years old and last winter the tank rusted thru and busted.
We have 11 cast iron “American Radiators” and they heat the house well.
The BTH will heat all the water to 150 degrees in about an hour and we don’t have to build a fire and wait hours.
The most impressive part is the Outdoor Temperature sensor. When it’s not that cold outside, the unit doesn’t turn on all the elements at once and slowly heats the water which saves a lot of electricity in the warmer months!
I’m looking forward to see how well it does when the temperature drops between 0-30 and it snows and I don’t have to go outside several times a day and load wood. I’m confident the Ghost Rider will perform!
Thanks.
The boiler works great easy install. But the tech support we got hold of was in French so not a lot of help.manual was easy to follow on wiring
Easy purchase - exactly what I needed
Plumber was very happy with it. So are we.
I’ve been using Everflux for some years now and it’s simply the best there is.
Excellent product for descaling tankless water heater.
Once again, great quick service
Good go,, 👍👍👍
Great service. Happy to find the products I needed.
Great place to order from. No complaints.
