PRLog - April 22, 2011 - HUDSON, Mass. -- Hudson, MA – The DN-420 Series Vortex Flow Transmitters from Clark Solutions are an excellent and economical choice for liquid media flow monitoring and control in ¼” to ¾” piping systems. These transmitters utilize the Kármán Vortex Trail principle of operation. In DN420 Transmitters, piezoelectric sensors embedded in an ETFE vane located downstream of the bluff detect generated vortices. The frequency measured represents the flow velocity. A flow factor is provided to convert frequency to volume flow rate for each model size. Each model is provided with a frequency/pulse output and a linear 4-20 mA output proportional to flow. Output is updated every 2 seconds. Available options include a 1000 Ohm RTD temperature sensor.
DN420 Flow Transmitter
DN420 Series Vortex Flow Transmitters are ideal for water and water glycol based heat exchange systems with flow ranges from 0.3 to 22 GPM. Wetted materials for flow transmitters include ETFE and EPDM, ASTM-PPA, Polyphthalamide, and ISO-PA6T/6I, Grivory 40% GF. DN-420 Series Vortex Flow Transmitters have an accuracy up to 50% fs: ≤ 1% fs from 50% fs: ≤ 2% of measured value.
