Especially in harsh weather conditions total and accumulated. total. like rain, snow, salty atmospheres and temperatures • Supply & return line: displays temp. and compensated flow rate. • Ability to process all types of signals: Sine wave (coil), NAMUR, NPN/PNP pulse, Reed-switch, Active pulse signals. Advantages • Robust aluminum or stainless steel 316L field enclosure (IP67 / NEMA Type4X). It is so rugged, a truck can even stand on it! • Intrinsically Safe available - ATEX and IECEx approval for gas and dust applications. • Programming can be done by your own crew, with the sensible menu-driven structure, saving cost and irritation. Know one, know them all! • Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors! PT100 - 2 or 3 wire. • Scaled pulse output according to differential / sum acc. total. • Negative or decreasing total indication. • Analog output according to compensated differential flow rate (consumption). • Full Modbus communication RS232/485/TTL. • Power requirements: Loop or battery powered, 8 - 30V DC, 8 - 24V AC/DC or 115 - 230V AC. • Sensor supply 3 / 8.2 / 12 / 24V DC. • Auto backup of

Your success counts The flowcomputer Model F127 has been developed to calculate The display has large 17mm (0.67”) and 8mm (0.31”) digits which corrected differential liquid volume at normal conditions for can be set to show flow rate, total and temperature. On-screen generic products. A typical application is the measurement of engineering units are easily configured from a comprehensive fuel consumption by engines for power generators, e.g. on board menu. The accumulated total registers up to 11 digits and is ships and locomotives. The usual difficulties encountered in backed-up in EEPROM memory...

Your success counts Overview application F127 The F-Series is your first and safest choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, salty atmospheres and temperatures between -40°C up to +80°C (-40°F up to 176°F). Fuel consumption calculation for diesel engines on board of ships or locomotives, generators or burners. Alternative basic model: F116. Signal input The flowcomputer measures the uncorrected volumetric flow and temperature in both supply and return line. The F127 will accept most pulse input signals for...

Your success counts Enclosures Various types of enclosures can be selected, all ATEX and IECEx approved. The F127 is supplied in an GRP panel mount enclosure as standard, which can be converted to an IP67 / NEMA Type4X GRP field mount enclosure by the addition of a back case. Most popular is our robust aluminum field mount enclosure which is also available with an extended backcover with undrilled preparation for direct meter mounting at the back side. It is so rugged, even a truck can stand on it! For the most challenging environments we have a durable high grade Stainless steel 316L enclosure....
