Flow Transmitters (AEM02)
About this class
Learn about the inspection and repair of electronic flowmeters by demonstrating maintenance procedures for vortex shedding, turbine, magnetic, and mass electronic flowmeters.
Prerequisites
This lesson is designed for participants familiar with electronic test procedures. An understanding of process operation is also required.
Description
This lesson introduces the inspection and repair of electronic flowmeters by demonstrating maintenance procedures for vortex shedding, turbine, magnetic, and mass electronic flowmeters. The lesson describes typical flow transmitter components, their functions, common malfunctions, and procedures for isolating a faulty component.
Objectives
Test and replace the amplifier unit, sensor, and bluff body of a vortex shedding flowmeter. Test and replace. The preamplifier unit, coil and other necessary components of a turbine flowmeter. Test and replace the coil, electrodes, and circuit board in a magnetic flowmeter. Jumper the appropriate terminals to simulate zero output and check the flowmeter output in an installed mass flowmeter. Test and replace the sensor and circuit boards in an installed mass flowmeter.
