Calibrating Flow Instruments (AIC04)

In Instrumentation

Details

This lesson demonstrates procedures for calibration of flow instruments.

Prerequisites

This lesson is designed for participants familiar with the basic principles of calibration including procedures, identifying instrument errors, and the standards for instrument performance. An understanding of algebra is also recommended.

Description

This lesson demonstrates procedures for calibration of flow instruments. The lesson specifically explains calibration of differential pressure transmitters, magnetic flowmeters, vortex shedding flowmeters, and mass flowmeters. Emphasis is placed on the proper set-up for calibration and the selection of the proper test equipment.

Objectives

Observe the correlation between differential pressure and flow rate. Identify and set up the measurement standards for calibrating a differential pressure transmitter. Perform a five point check on a differential pressure transmitter. Interpret the results and correct instrument errors. Set up a square root extractor for calibration and adjust its zero. Observe how a magnetic flowmeter generates the output voltage as a result of the input voltage. Calibrate a magnetic flowmeter. Observe how a vortex shedding flowmeter generates output resulting from input. Set the course span jumpers correctly and determine proper calibration of a vortex shedding flowmeter. Connect the interface device to the smart mass flowmeter. Set the interface device to the smart mass flowmeter. Modify the upper and lower range values. Download the new information to the transmitter. And test the mass flowmeter for auto zero.
