Are PD Meters a Dead Technology?


For LACT units, Coriolis has become the dominant technology of choice. Reasons for this are: 1. cost of ownership, 2. reliability, and 3. meter intelligence.

Cost of Ownership = initial price + install cost + maintenance cost

Reliability = performance over range of varying parameters

Meter Intelligence = smart transmitter with multiple measured variables + meter function diagnostics.

So does this mean positive displacement is a dead technology? After all, PD meters do have their advantages: 1. increased accuracy with increasing fluid viscosity, 2. low pressure drop, 3. ease of installation.
