The little knowledge for today's science popularization is: how to set the instrument coefficient of gas turbine flowmeter. I believe many friends know that the confirmation of instrument coefficient can directly affect the measurement accuracy of gas turbine flowmeter. Let's take a look at how to set the coefficient of gas turbine flowmeter.
Taking the YK-LWQ series of common measuring instruments as an example, gas turbine flow meters are generally powered by batteries, and this one is no exception. Let's first take a look at its appearance and composition.
From the appearance, there is no special feature compared to other instruments. The top is a display head, and the bottom is a sensor body. The connection method is flange installation. When we open the back cover of the instrument, we can see the internal structure of the junction box as shown in the following figure:

Observant friends have noticed that the left row contains mechanical buttons that can be used to debug instrument parameters, the top row contains output wiring terminals, and the right row contains a battery that supplies power to the gas turbine flowmeter.
Next, let's take a look at how to set the instrument coefficient.
Main menu of gas turbine flowmeter
When in the main menu, you can press the SET button inside the junction box. When pressed for the first time, the screen will light up, and when pressed again, it will jump to the output password interface. The setting password for this gas turbine flowmeter is 1234.
Password output interface for gas turbine flowmeter
Add the functions of the following buttons: SET for confirm and next page, RIGHT for move, UP for number increase, ESC for exit and return. Based on the functions of these buttons, directly input the required values.
After the password output is completed, simply press SET to confirm and the following will be displayed:

When on this interface, you can press the SET key to scroll down until you find the instrument coefficient item that needs to be set. When you find it, you can directly press the RIGHT key to move the cursor, then press the UP key to modify the value. After modification, press the SET key directly to confirm. That's it.

Summary: To set the instrument coefficient of a gas turbine flowmeter, simply press the confirm button on the main interface to enter the password, then find the instrument coefficient on the page, press the move button, and then press UP to modify the value. This is a basic process.
Regarding the use and parameter settings of gas turbine flow meters, we welcome everyone to communicate together.
