The Origin Of Chlorine And Chemical Feed Scales

As with many small companies, Force Flow was established out of need for a product that could better serve the specific needs of a particular market and application.

Up until the mid 1960's, the municipal water and wastewater market occasionally used mechanical platform scales to monitor the contents of chlorine ton containers. These 'pit mounted' industrial platform scales were not easy to install, required regular maintenance and calibration, did not facilitate easy handling of the tanks, and did not have alarm or remote monitoring capability. On top all this, they were extremely expensive!

In 1967, Dave Nelson was a young instrument salesman and recognized that there was a need for a better product. His past experience as a scale mechanic and a sense for creativity gave him the ability to develop the rugged and reliable hydraulic CHLOR-SCALE® that has become the industry standard worldwide. Dave's leadership and innovation pioneered the use of level alarms and remote mounted instrumentation to reduce operator exposure to chlorine, integrated roller trunnions for ease of valve positioning, and the simple 3-point pivoted platform design to make installation and operation a breeze. These basic features of Dave's original CHLOR-SCALE design have been imitated, but never equaled, in many countries around the world including China, England, Germany, India, Canada and of course the USA. As the saying goes, 'Imitation is the best form of flattery!'

Force Flow has continued to take the lead as the innovator in chemical monitoring with products like our WIZARD 4000® Chemical Inventory Management System and our CHLOR-SCALE 150® for cylinders. Perhaps as important as being a technology innovator is our commitment to customer service through our exclusive 5-YEAR WARRANTY and PERFORMANCE GUARANTEE™.

In 1996, Dave's son Mark took over the operation of the company after 12 years employment and a lifetime of literally 'growing up' with scales. With an experienced and energetic management team in place, Force Flow is excited about the technological innovations that will continue to shape our industry in the 21st century.
