Flow Rate Meter and TotalizerPrecision Digital’s PD6830 ProtEx-RTP Pulse Input Rate/Totalizer with a rugged, explosion-proof, NEMA 4X enclosure is designed for quick and easy display of local or remote flow information in hazardous areas or the harshest safe-area applications. The SafeTouch through-glass buttons allow operation without removing the cover. Flowmeter k-factor units are automatically converted to the desired display units; this means no conversion factors are needed. The pulse input accepts a range of flow transmitter signals, including mV input from a magnetic flowmeter, as well as high frequency signals. The PD6830 includes backlighting and two open collector outputs as standard. The meter has FM, ATEX, CSA, IECEx, and CE approvals and is housed in a rugged, cast aluminum NEMA 4X enclosure.
