Measurement of heat quantity

• Order code: S11

This function calculates the total fuel calorific value of the measured fluid. Engineers can either use a constant value of the calorific value of the fluid or rely on an additional device like a gas chromatograph to provide the instantaneous calorific value through the analog input of the FCT040 transmitter. Then, we calculate the total calorific energy of the fluid based on its flow.

Tube health check

• Order code: S12

Tube health check monitors key diagnostics, including tube stiffness, driver and pickups. Self-verification alerts to potential performance issues due to unplanned process events, for example gas or vapor breakout, or solid deposits building up in the tubes. The user defines verification frequency and alarm behavior. Verification results indicate whether preventive maintenance action is required.

Petroleum measurement function

• Order code: S14

The Net Oil Computing (NOC) function provides real-time measurements of water cut and includes American Petroleum Institute (API) correction according to API MPMS Chapter 11.1.

Oil sometimes contains entrained gas. SITRANS FC flowmeters measure the density of the combined emulsion oil and gas, which is lower than the oil density. The NOC function includes a Gas Void Fraction (GVF) parameter to be set.

Viscosity function

• Order code: S15

Viscosity is sometimes can use to activate other processes like fluid heating systems.

Engineers calculate the viscosity estimation by comparing the measured pressure loss with the calculated value between two points of the pipe. To use this function, we need a differential pressure transmitter. We connect its output to the analog input of the FCT040. Through an iteration process, we determine a viscosity value.

Standard concentration measurement

• Order code: S16

Used for concentration measurements of emulsions or suspensions when density of the fluid involved depends only on temperature.

The standard concentration measurement can be used for many low-concentration solutions if there is only minor interaction between the liquids, or if the miscibility is negligible.
