Application Notes & Measurement Protocols

The Lending Library application notes & measurement protocols describes measurement tips for specific building applications using tools from the CUNY Field Equipment Lending Library (FELL). The application notes serves as a primer for first-time users and as a reference for experienced users needing help with identifying specific operations.

Variable Frequency Drive

A variable frequency drive or variable speed drive is a type of adjustable speed drive used in electric mechanical systems to control motor speed and torque by varying accordingly to the input or set-point indicated.

Click here for the Variable frequency drive monitoring slide deck, with tips on how to monitor VFD’s within your facility.

Equipment to use:

Application: Electrical
Tool: Dent Elite Pro Energy Logger
Application: Motor
Tool: Motor on/off status
Application: Water systems
Tool: Ultrasonic flow meter

Steam Traps

A steam trap primary mission is to remove condensate and prevent air from escaping from the distribution system. Monitoring these traps and identifying which one’s need to be replaced are crucial for an efficient steam system.
