Johnson Degree Day Systems

    Johnson Degree Day has been meeting the demand for an accurate way to calculate heating degree days for 46 years.  Our fuel demand meters measure combined effects of temperature, wind, and sun to give you "effective" degree days!  This makes our products an essential part to degree day delivery systems. You'll be able to make larger fills and make less deliveries, thus putting more money in the bank.

    We have three generations of Degree Day Meters. The first generation is the model ZZW. The ZZW was built in the late 50's to late 70's, and a large number of these meters are still currently in operation. The second generation of Johnson Fuel Demand Meters is the D-10 and the FD-50. This was a step up from a mechanical meter to a meter that is based on integrated computer chips (IC's). These meters were built in the late 70's to late 80's. Most of these meters are still in operation today also. Currently, we are in the third generation of Fuel Demand Meters - the F-90 and the F-90H. Because the D-10 and the FD-50 were very susceptible to power surges and electrical fields, we went back to a mechanical based meter. These meters are made to be accurate and reliable.

    We are currently taking orders on the F-90 and the F-90H. Please continue through our web site to find out more about the F-90 and F-90H. Find out how they work and how they can save you money!

    If you would like to place an order for a F-90 or F-90H, please call us at (269) 343-1221, and we'll be happy to take your order for you!
