Water Level Detection System with Automatic Water Maintenance
Prevent Boiler Damage and Allow
Longer, Safer Runs
Water sight glasses in our model steam engines have many limitations and are often inaccurate and difficult to read and the train always has to be stopped to take a reading. This Water Level Detection System senses when the water in a boiler approaches a low level and is in danger of damaging the boiler by changing the normally Green LED to Red. Then water can be added through a Goodall valve. Also an Electric Water Pump can be controlled to automatically add water as determined by the Sensor Circuit. When an axle pump is used, a solenoid valve in the bypass is activated when the System senses need for water to maintain water in the boiler.
ADVANTAGES OF THE WLDS SYSTEM Simple, accurate and easy to install Works with distilled water - No need to add tap water as in other systems Uses an RF coupling circuit which avoids corrosion and/or plating of the probe A continuously visible Red/Green LED indication assures a "working system" in which the water level can be monitored without stopping the train Faster “steam up time” no need to completely fill the boiler initially. Allows long, safe runs Can be used to control water flow with axle pumps In boats, water level can be monitored "from the shore”. The miniaturized system is easy to install. An on/off switch and an adjustable continuing pump control are included to prevent excessive pump cycling. The system is easily installed in a locomotive tender or steamboat. A complete set of instructions, including the easy installation of the probe into the boiler, is included.
For installation in Accucraft Locomotives that have a mounted sight glass in line with the top of the flue, a special probe and plug is available which replaces the sight glass and eliminates the need to drill a hole in the boiler. Therefore no permanent alterations to the boiler are required.
The price of the complete system as shown is $125.00* plus $10.00 S&H. A set of 2 drills and a tap is available for $10.00 for those not having access to those tools. The Accucraft special probe is available in lieu of the standard probe for $60.00* For further information, please send an Email to firstname.lastname@example.org For immediate shipment, make a check payable to Bill Ford and send to: Bill Ford / B.
