Ultrasonic waterfalls?
I don’t suppose you are likely to encounter these but if you do, servicing procedures will be similar to those described in the section: Ultrasonic humidifiers. (From: Roger Vaught (vaurw@onramp.net).) At a local shop they sell small water fall displays made from limestone in a marble catch basin. These are made in China. They use a small water pump for the flow. When I first saw one I thought the store had placed dry ice in the cavity where the water emerged as there was a constant stream of cloud flowing from it. Very impressive. It turns out they use the ultrasonic piezo gizmo to make the cloud. The driver is a small 3 X 5 X 3 inch box with a control knob on top. If you look into the cavity you can see the piezo plate and a small red LED. The water periodically erupts into vapor. I haven’t been able to get a close look at the driver so I can’t tell where it is made or if there is a product name or manufacturer. They will sell that part of it for $150!
