An alternative to turbine and paddlewheel insertion flow meters, Series TDT delivers accuracy over a range of pipe sizes. These units have an insertion mounting into a 1.5" NPT and do not have any moving parts to wear, break or clog. The dispersion transmitter measures low flow rates due to the applied calorimetric principle and can be used for the metering of all fluid media, including water, oil, aggressive media, paste, glue, sludge and grease. Due to an adjustable insertion mounting, one model is suitable for pipe sizes of 1 to 24", and with available extensions, it can be used for pipes sized up to 75" dia.
