buy Lyrical dance costumes online The RCM Digital flow meter display is a 2 wire loop powered 4-20mA DC transmitter features 7 digits for flow rate and 11 digits for accumulated total. On-screen engineering units are easily configured, while different units for flow rate and total can be displayed simultaneously. A wide selection of options further enhances this models capability. Optional back-lighting is available for easy viewing.

Wet/wet differential pressure sensor is protected by an isolated stainless steel diaphragm for measuring liquids, gases and conductive flow media.

skelaxin buy 2014 The digital display can be connected as a remote display (option DR-1) to our 4-wire transmitter output option W (4-20mA linear output signal), 2-wire loop powered transmitter option W2 or W3 (4-20mA loop powered signal) output is proportional to flow rate squared or our 2-wire loop powered transmitter option RW3 which is self-contained and complete.
