Guided Wave Radar (GWR) or magnetostrictive level transmitters are ideal for interface measurement. They can detect two distinct liquid layers (oil on top, water on bottom) based on the difference in dielectric constants.

High-pressure electromagnetic flow meters (rated for 2500# ANSI or higher) are often used for conductive water injection. For non-conductive fluids or extremely high pressures, Coriolis or Ultrasonic meters are preferred.

A Multivariable Transmitter or a Vortex Flow Meter with built-in pressure and temperature compensation is essential. It automatically corrects the volumetric flow to "Standard" or "Normal" volume (SCFM/Nm3/h) for accurate mass balancing.

No. Standard stainless steel can suffer from sulfide stress cracking. Specifications must include a Gold-plated diaphragm or, more commonly, a Hastelloy C diaphragm compliant with NACE MR0175 standards for H2S service.

Coriolis mass flow meters are the premier choice for custody transfer due to their high accuracy (typically 0.1%) and ability to measure mass directly, independent of fluid properties like viscosity or density changes.

Ultrasonic level sensors are cost-effective and common for mud pits. For pits with heavy vapor or foam, or for higher precision, non-contact radar sensors are the superior, low-maintenance alternative.

Combining high-accuracy flow meters at both ends of a pipeline section with pressure transmitters allows a control system to detect imbalances (mass balance method) or pressure waves that indicate a leak.
