Industrial flow meter
DFM Industrial is designed for accurate flow rate measurement of fuel and other liquids used in sea and river vessels, fuel delivery from truck tankers, in high-power diesel generator sets and boilers, in petrochemical, utilities and other industrial applications (IIoT).
Model line of DFM Industrial flowmeters includes autonomous counters with electronic display only (LCD) and flow meters with LCD and output interface cable for sending data to recording devices, displays, tracking units, telematics units.
DFM Industrial flowmeter is mainly used as a part of ship monitoring and machinery operation tracking systems, and as part of Industrial Internet of Things (IIoT) systems, also as autonomous solution for fuel/ liquid consumption.
Tasks
Fuel (liquid) consumption measurement
Machine running time tracking
Optimization of fuel (liquid) consumption
Preventing thefts of fuel/liquid from pipeline
Engine testing for fuel consumptionAdvantages of DFM Industrial
Embedded flow computer, built-in battery, electronic display
DFM Industrial shows measured data on electronic display: 17 Counters of fuel / liquid consumption and engine/pump operating time (see the full list). Raw data is processed by embedded flow computer, which also allows to connect 2 pieces of DFM Industrial for differential liquid consumption measurement. Built-in battery provides autonomous fuel/ liquid consumption measurement even if external power supply is switched off.
Protection against tampering
DFM Industrial records special Counters for protection against tampering attempts:
- “Interference” Counter protects DFM Industrial from magnetic field impact aimed on stopping fuel consumption measurement.
- “Tampering” Counter registers attempts of third party to tamper flow meter data by generating artificial fuel/ liquid consumption (e.g. by blowing the air through measuring chamber).
- “Number of Interventions” Counter keeps track of number of magnetic interference attempts.
Compliance with S6 Technology
DFM Industrial can be connected in one S6 network with fuel level sensors to provide detailed reporting on fuel/ liquid consumption. Operation parameters and Counters can also be transferred to S6-compatible display and recording units – e.g. MasterCAN Display 35, CANUp or GPS trackers/telematics units.
Edge/fog raw data processing using IoT Burger Technology
Built-in software of DFM Industrial flow meter converts raw data (inputs of physical environment) into ready-to-use information – Parameters, Counters and Events – on fuel/ liquid consumption, operation time, “Tampering”, “Interference”, “High/ low supply voltage level”, “Ignition on / off” Events.
IoT Burger Technology also allows to make advanced configurations of DFM Industrial:
- configure correction coefficient of instant flow rate;
- configure coefficient of volumetric expansion of liquid;
- carry out differential or summarization liquid flow rate monitoring in two and more pipelines within one measurement system.
