SCREW PUMPS Flow Meters MPV Series Display & Data Management 7 #DriveLineHarmony S311DS The S311DS represents the most affordable and reliable solution to the demand for local displaying the flow rate. Unit includes several features, like but not limited to totalizer and repeated signal. S311DS features: » Digital Universal opto isolated digital input; admitted types: reed, npn (2 wires or 24 V), pnp (24 V), NAMUR, photoelectric, Hall, 24 V input, TTL, variable reluctance. » Digital input signal frequency measurement from 0.00015 Hz to 10 kHz. » Increment or decrement totalizing of the digital input signal. » View of the frequency measurement and/or totalized value. » Programmable retransmission of the input value frequency by the isolated analog output (voltage or active/passive current). » Retransmission of the totalized value by the isolated digital output (Open Collector). » Totalizer value is saved on non-volatile memory. » Filter programmable at 20 levels to stabilise reading. » Two relay outputs (available on the optional card) for alarms signalling. » Easy navigation on the programming Menu by three buttons on the frontal panel. » 4 digits display. » Quick configuration of the alarm thresholds by the Quick Alarms Menu. » Display contrast settable. FD20S The Display unit FD20S represents optimal solution for monitoring and managing signals coming from different sources, with specific care to an user friendly interface, to reliability and stability and, last but not least, price oriented solution on the market. Easy and simply setting is supported by pre-set parameters of all SEIM flow meters MPV Series. (setting menu grant immediate selection of the I/P source). Since the capability by FD20S to manage for multiple input signals, it represents also optimal choice wherever is necessary to relate the volumetric data from the flow meter to other parameters, like pressure and temperature. FD20S features: » 3 x 4-20mA channels. » 1 Thermistor input. » 1 Pulse input configured to interface with the Seim MPV flow meter Series MPVA/MPVK..2 line 16 digit LCD display with back light. » Easy three-key setting via front panel. » Loop powered 4-20 mA output flow rate. » RS232 data communication HI, LO. » Dual Relay output with LED indication. » ¼ DIN 43700 Standard (96 x 96 x 47) instrument case with panel mount clamps. www.jbj.co.uk/flow-meters.html
