Multi-Variable Mass Flow Calculation Setup

 

Customer Issues

• Installation cost of multiple field devices is high.
• Mass flow measurement is expensive.

 

Utilize EJX910A/930A + Flow Navigator

• From one multi-variable transmitter, you can measure differential pressure, static pressure, temperature and mass flow. The total cost is greatly reduced.
• Flow Navigator software provides a simple, user friendly method to configure the mass flow measurement.

 

Utilize FieldMate

• Flow Navigator has a step by step interface based on FDT/DTM technology. You can set the data by simply selecting the primary element, and inputting the flow rate information.
• You can copy the configuration of one transmitter to another transmitter to help with multiple configurations.

 

EJX Multi-Variable Transmitter Outputs

① In the case of HART digital / FOUNDATION Fieldbus /Modbus, these types of outputs can transmit multi process values at the same time.

② In the case of Analog signal (4-20mA), a multiplexer can be used to convert up to three values from HART signals into 4-20mA signals. The transmitter can transmit up to four values in conjunction with the original signal.

③ In the case of ISA100(wireless), the ISA 100 adaptor can transmit up to four values from the HART signal without reconstructing an existing line.

The measurements that EJX multi-variable transmitter can transmit

Protocol	DP	SP	Ext. TEMP	Other TEMP	FLOW	Total Flow *4
HART *1	●	● either H or L	●	● Capsule Amplifier Flange (/DG6)	●	●

*1：In 4-20mA, output is one signal by one value。In HART, output is one signal by multiple value (up to four value).
*2：Number of output values is up to five.
*3：Flow, total flow, other temperature（flange）as output are not supported.
*4：Total flow is using HART or the pulse signal. 4-20mA signal is not supported. In FOUNDATION fieldbus, output is using IT function block.
