Flomatcher was started in 1957 using a patented Liquid Rheostat for manufacturing variable speed motor control systems. Our proprietary rheostats are used to smoothly and steplessly vary the speed of pump motors to match the constantly changing demand for water flow rates in a wide variety of exacting applications. Flomatcher now has well over 8,000 installed units controlling motors ranging in size from 4 hp to 4,000 hp from the cold temperatures of Alaska to the high humidity of Hawaii. There is a wide base of installed systems in North and South America. Flomatcher sales, repair and service is provided through a network of sales representatives across the United States and Canada. Some typical applications where liquid rheostats may be found are in water treatment facilities, waste treatment plants, high-rise potable and fire control water systems. The technology behind the liquid rheostat is simple and low maintenance there are no moving parts. Maintenance costs are the lowest in the industry because of the principle of operation and simple components. A skilled electronics technician is not required for operation, maintenance, or repair. The liquid rheostat can be repaired in the field by on site personnel with hand tools that are standard equipment in any plant. Many installations have been running their Flomatcher equipment for well over 25 years without any problems. These have proven to be the most reliable systems available today, particularly in areas with poor power quality and limited access to skilled technicians. The voltage spikes, frequent brownouts, power outages, and lightning strikes that wreak havoc on solid state drives are not a problem to the rugged liquid rheostat. An added advantage is that liquid rheostats do not generate the harmonic problems that are such an issue today with solid state drives.
