But the new flow switches developed by Thomas Products, LTD., a leader in flow switch technology, can eliminate or minimize the possibility of such accidents occurring. With a wide array of applications, from acid water neutralization to super chlorination to boiler water treatment applications, whenever a metering pump is used, a positive displacement flow switch should be installed.
