Force Flow

Chemical Monitoring Equipment for Water & Wastewater Treatment Plants

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. Another innovative initiative by Force Flow has been with the use of Chemical Feed Scales.


When feeding chemicals, such as Fluoride, Polymer and Sodium Hypochlorite, it is imperative that you have a way of accurately tracking chemical usages and feed rates. In fact, many government regulations require you to document chemical usages, and there is no more accurate method than using a weight-based chemical monitoring system.

Compared to intrusive tank level technologies, weight is an inherently more accurate means of measuring level contents because it is independent of vessel shape, temperature, corrosive fumes and specific gravity of the contents. Using the CHEM-SCALE for your inventory management results in an inexpensive, non-contacting, highly reliable method of tracking chemical levels, usages and feed rates.

These heavy-duty platform scales are available with our chemical resistant Tuf-Coat finish or in 316 stainless steel and have adjustable tank anchoring/restraint clips mounted directly to the scale platform.

The restraint clips provide lateral stability and can be used in conjunction with our hold down straps to further secure the tank for extreme protection in the event of a natural disaster such as a flood, earthquake or high winds.
