Model Number

EMI2

The EMI2 Flowmeter measures stroke-by-stroke instantaneous volumes of an injector/pump system.

This product has been developed for Bosch and manufactured by EFS. It may be ordered directly from EFS under certain conditions.

System description

The injection flow measurement bench is composed of a mechanical part and an electronic part (see picture).

The mechanical part includes the injector holder and the measuring sensor.
The electronic part is in the form of a 19' 3 U box which can be used on a work surface or fitted in an instrumentation cabinet.

Use

The adjustment liquid is injected into a closed piston-cylinder unit where a back-pressure fom 0 up to 100 bars can be applied.
Once the injection is finished, the piston displacement representing the injected volume is measured. The injected volume may range from 0 to 600mm3 ; it is measured with an accuracy of 0.6mm3.

The instrument simultaneously measures pre-injection, main injection as well as post-injection (when applicable) and displays them as an instantaneous value, averaged or cumulated for a given number of injections. It also features automatic setting of the angle adjustment and the angle measurements. Adjustment of measurement points can be carried out in manual or automatic mode.

All measurements carried out one after the other by the instrument are available on analog outputs which can be set up according to user requirements. The "user-friendly" interface, by means of the built-in screen and keyboard, facilitates communication with the instrument and provides flexible parameter setting.

It is also possible to control the device by means of an external computer or an automatic controller via an RS 232 or IEEE 488 link (optional) for integration in an automatic bench.
