Specifications include, but are not limited to: Electromagnetic 6” Bi-directional Liquid Flow Sensors and 3 Coupled Signal Converters. This technology will be used on an agricultural slurry manure injection tool and separately in both indoor and outdoor agricultural classroom instructional environments. These electromagnetic liquid flow sensors must be of welded full bore flow tube stainless steel pipe construction (or alternatively, stainless steel/Teflon), fitted with a grounding ring 3 mm/0.1” thick with a cylindrical neck of 30 mm to prevent damage to the stainless steel liner, and fitted with 6” diameter 8-bolt flanges and 6” gaskets on both ends for coupling to fixed 6” diameter 150 lb. 8-bolt pipe flanges.
