Continuous Level Transducers for Reliable, Economical Tank Level Monitoring
|
Application Example
For one customer, Madison's Continuous Level Transducers are custom-designed with a specially weighted float to "ride" on the interface between oil and water in an oil-water separator. By 'weighting' the density / specific gravity of the float,
Madison's engineers can provide a float that sinks through the lower density oil but remains buoyant in the higher density water, thereby monitoring the interface of the two dissimilar fluids. The weighted float principle remains one of the most direct, reliable and economical means of sensing liquid interfaces like chemical emulsions, slurries and other layered liquids. |
Madison's vertically mounted 'C Series' float transducers offer a reliable and economical means of tank level monitoring suitable for a wide variety of applications and liquids. Available with either brass or 316 stainless steel mounts and stainless, polypropylene or Buna-N floats, the C3957 features a 5mm resolution, while the C3946 offers a 10mm resolution. Each model has a simple two- or three-wire connection.
 The C Series sensors contain a chain of equally spaced magnetic switches and resistors in sensing lengths to 96 inches. When activated by the moving magnetic float, the switch chain creates a variable resistance signal that is then converted to a proportional voltage (1-5VDC) or current output, (4-20 mA) through a 24VDC powered circuit board located within the compact stem. The output can then be routed to a meter, programmable controller or other readout or receiver. The float transducers can also be equipped with separate high and/or low float switches for independent alarm signals.
Unlike many solid state level transmitters, the C Series is unaffected by conductivity or dielectric properties of the liquid. "If it floats . . .it works!" The integral circuit board design and robust brass or stainless tube resists shock and vibration, making it ideal for off-road vehicle fuel tanks, generator tanks and more.
The "C Series" offers a low-cost, buoyancy-based alternative to other level sensing technologies and compliments Madison's ever-growing selection of dependable OEM-priced products.

Madison At AHR EXPO - Chicago, January, 2012
 Madison Company and its sister company, FloodMaster, will be exhibiting at the 2012 AHR Show at the Chicago McCormick Center, January 23-25. This will be our second appearance at this venerable industrial show serving the HVAC market and related industries. Our first appearance last January at the show in Las Vegas attracted hundreds of visitors to our booth and generated enthusiastic interest from old friends and new contacts in Madison's liquid level products and FloodMaster's leak detection shut-off systems.
Among the applications discussed included condensate level, chillers, cooling towers, refrigerant control, heat exchangers, liquid separators and boilers. The audience included HVAC equipment manufacturers and designers, municipal wastewater supervisors, engineering firms, contractors, facility managers, equipment retailers and distributors.
This year we will again have working products on display with sales and engineering staff on hand to discuss practical applications and answer questions. We look forward to meeting with our many friends in attendance. If you would like a free pass to the show, please contact Frank Smith at (203) 488-4477 ext. 113 or
