MAXIMUM VELOCITY

10 m/s (33 ft/s)

MINIMUM UPPER RANGE VELOCITY FOR 100% OUTPUT

0.5 m/s (1.65 ft/s)

MINIMUM MEASURABLE FLOW RATE

0.01 m/s (0.033 ft/s)

Low Flow Cut-Off

A low flow cut-off algorithm holds the pulse output,rate indicator, and digital measurement at zero when the measurement signal falls below 0.01 m/s(0.033 ft/s). The analog output remains active at zero flow, unless specifically configured to go to zero when flow rate falls below a user-configured value.

FLOW RATE- UNI- OR BIDIRECTIONAL

+ or - Rate in Engineering Units
+ or - Rate in% of Upper Range Value

TOTALIZATION

+ or - Bidirectional Total (8 digits)
Net Total (8 digits)
Net Inventory Total (10 digits)

Power Consumption

Power for the flow measurement system (IMT96 and 2800 Series Flowtube) is less than 100 VA,regardless of tube size.

Output Damping

Field programmable from 0 to 99.9 s. This feature is used for reducing the frequency response of the transmitter as required by the process.

Self Test

In the background to normal flow calculations, the system continuously performs self-test checks. If a fault is found that makes flow calculation impossible,the outputs go “LO” or “HI” based on configuration choice. A diagnostic message identifying the problem is also issued. This message can be read on the local LCD Indicator, with the PC-based Configurator, an I/A Series Workstation, or a HART Communicator.

Preset/Calibration

The transmitter may be used as a 4 to 20 mA or pulse generating source to check and/or calibrate other instruments in the loop, such as indicators,controllers, and recorders. This feature may be activated by pressing keypad buttons. The output signals can also be adjusted to any value, remotely,via the PC-based configurator or HART Communicator.

Ranging

The MagEXPERT Transmitter is easily adjusted for the desired flow rate units and to the required upper range value. This range data may also be keyed in through the PC-based configurator or HART Communicator.

Output Signals

Three electrical output signals are available - Digital,4 to 20 mA, and Pulse. The Digital Output utilizes either HART or FoxCom protocol. All three output signals are available simultaneously except that the 4 to 20 mA output is not available when HART is configured for Multidrop operation, or with 4800 baud FoxCom.
