Overview

Main points that covered in the course:1- We will present some types of level measurement instruments. There are two main categories: - Point level instruments, which produce digital signals and are used to detect a specific level (such as full or empty). - Continuous level instruments, which produce analog signals and measure the level across a range.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,2- Case study tutorial:How to measure fluid level of open vessel using ultrasonic level (non contact sensor)Open vessel: Tank level control system is widely used in automation , common application in industry.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,3- we have 4 points in open vessel application:a. Features and conditions of the open vessel - understanding the design and environment of the tank. b. Mounting the ultrasonic sensor and installation conditions - where and how to properly install the sensor. c. Entering variables into the transmitter - this step is known as programming or commissioning.d. how to connect the sensor & the transmitter using terminal blocks and electrical wiring. Proper wiring ensures accurate signal transmission and safe operation.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 4- after mounting / install sensor fdu90 from Endress Hauser, in the last lesson.- Connect this sensor cables with transmitter fmu90 , i show you terminal blocks & electrical wiring.- Switching on the measuring device.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,5- Access to the operating menu via the local display:Elements of the display and operating module:Configuring the measuring device:i show u the main interface of fmu90 transmitter from Endress + hauser brand:1- Soft key symbolssoft shortcut menus at lcd:info , menu2- Keys3- Light emitting diodes to indicate the relay switching states4- LED to indicate the operational state5- Display symbol6- Parameter value with unit (here: primary value)Symbols for operating state,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 6- press right hard key to get to: menu soft keymain menu screen appear with these submenus:- level- safety settings- relay/control- output/calculate- device properties- system informat- display- sensor managementgo to level menu , then u see 3 submenus- basic set up- extended calibration- simulation,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
