IIoT Headwinds
� Viability
� Cost must be reduced by 80-90 percent
� Many sensors require wires for power
� Important parameters are already
measured and/or under control
� Sparse documentation of results
� Measurements are often not simple

Velocity Profile
Flow
Velocity Profile (distorted)
�A distorted velocity profile can introduce significant errors into the measurement of most flowmeters

Velocity Profile
� Good velocity profiles can be developed
� Straight run upstream and downstream
� No fittings or valves
� Upstream is usually longer and more important
� Flow conditioner
� Locate control valve downstream of
flowmeter

Anecdotal IIoT Examples
� Vortex shedding flowmeter measurement
becomes unstable when pump motor
bearing needs to be replaced
� Flow drops off as heat exchanger plugs

IIoT Practice
� Limited IIoT adoption
� Flow sensors are relatively expensive
� Not Lick and Stick
� Big Data in the Cloud for viable sensors
� Digital Enterprise trend continues

IIoT Practice
� Benefits typically cannot be accurately
quantified prior to installation
� Difficult to justify expenditures
� Partial implementation
� RESULT: Better decisions… but not
quite as quickly as initially thought
