Delta D on steam line can be monitored using differential pressure transmitter.

• Install a differential pressure transmitter across the steam line.

• Calibrate the transmitter to measure the pressure difference between two points.

• Convert the pressure difference to delta D using the known properties of the fluid.

• Monitor the delta D reading regularly to detect any changes in the steam line.

• Take corrective actions if the delta
