IFR INECTION FLOW AND RATE
PRESENTATION
The IFR (Injection Flow and Rate) is a device for measuring injection volume on a stroke-bystroke basis.
It is particularly adapted for monitoring the high-energy multi-stroke injection systems found on modern diesel motors.
ADVANTAGES
- Instantaneous flow measurement of up to 10 injections/revolution.
- Real time display of the injection rate curve.
- Injection rate identical to the measurement given by a «rate tube».
- Analysis of the injection rate and time measurements.
- Mass measurement accuracy regardless of injection conditions : pressure, speed.
- Back pressure can be regulated from 5 to 100 bars.
- Injection measurement during 180° rotation from the pump (360° motor).
DEVICE STRUCTURE
The IFR system is made up of :
-a mechanical element including measurements of volume (mass), pressure and temperature.
-an electronic element which manages the measurement cycle and carries out all the necessary calculations at each revolution.
PRINCIPE DE FONCTIONNEMENT
The injected fluid is collected in an injection chamber maintained at a constant, static pressure. This injection back-pressure can be regulated from 5 to 100 bars.
The increase of the mass in the injection chamber causes an increase in the instantaneous pressure, providing an image of injection volume.
At the end of the injection cycle, the injected fluid is transferred into a volumetric measurement chamber which performs an accurate measurement of the total injected mass. The pressure signal from the first chamber is analysed to determine all the mass measurements, the time intervals and the duration of each injection. |

The latest product line developed by Teledyne Hastings Instruments is the digital version of the high capacity flow instruments. These new digital instruments allow measurement and/or control up to 10,000 slm. The new line complements the existing lower flow Digital Metaline(R) (5 sccm to 30 slm).
The two product lines, Digital Metaline and the new high capacity digital flow instruments, offer flow meters and controllers from 5 sccm to 10,000 slm, with superior accuracy. The lower flow Digital Metaline units have all-metal seals. A 4µ-inch Ra finish is available for flow rates up to 10 slm. Multiple gas calibrations and stored gas conversion factors are key features that set these instruments apart from the analog versions.
Both the Digital Metaline and the high-capacity digital flow instruments feature flexible operation with ±12, ±15 or 24 VDC power supply and transparent operation in analog or digital modes. All digital units are available with RS232 or RS485 interface with baud rates up to 19.2 kbaud. In addition, the instruments offer convenient self-diagnostics including warnings and alarms for flow, sensor, and valve status.

| Two technologies - thermal mass and multivariable vortex mass - provide the best solutions for most mass flow measurement applications. Thermal mass flow meters are ideal for monitoring low pressure gas flows. The multivariable vortex mass meter measures a wide range of gas, steam and liquid flows. |
|
A comprehensive range of thermal mass gas meters for flows as low as 0-10 SCCM and up to emissions stack-flows are available. These measure mass directly not requiring the measurement and computation of pressure and temperature. The meters have a wide measurement range.

|
| The CM Series mass flow meters utilize industry's well recognized high accuracy standard, Coriolis technology. The core operating principle of this technology is that fluids flow through a vibrating tube which then causes a deflection of the flow tube proportional to mass flow rate. It is suitable for use with liquids, gases and slurries. Models are available that will measure mass flow, volumetric flow, temperature and density. Unaffected by variations in pressure, temperature, density, electrical conductivity and viscosity, the CM Series provides extremely accurate mass flow measurement over wide flow ranges. The series is comprised of three (3) models which differ by their choices in flow range, wetted parts, accuracy, pressure ratings, density measuring, and other optional functions and features. |
