Gas Turbine Flow Meter

Introduction:

Gas turbine flow meter is a new generation of high-precision and high-reliability gas precision measuring instrument, which is based on the advanced technology of flow meters domestic and abroad. It has excellent low-pressure and high-pressure metering performance, various signal output modes and low sensitivity to fluid disturbance. It is widely used for natural gas, coal-based gas, liquefied gas and other gases application.

Features:

(1)LCD HD display;

(2)Digital board,stronganti-interference ability;

(3)Support display to rotate 360°;

(4)Easy to read data in differentdirections;

(5)Dynamic detect temperature&pressure data;

(6)Automatic T&P compensation ;

Gas Turbine Flow Meter Advantages and Disadvantages:

(1)Gas turbine flow meter is with advanced rectification technology and dust-proof structure.

(2)It is with built-in temperature and pressure sensors which can achieve automatically compensation to make sure high accuracy.

(3)Gas turbine flow meter provides good solution for custody transfer between parties.
(4)Compared with precession vortex flow meter, gas turbine flow meter is with low pressure loss, low initiating flow and wider measurement range.

(5)The display of gas turbine flow meter support to rotate 350°, easy to read data in different directions.

Installation Requirement for Gas Turbine Flow Meter:

(1)In order to obtain a stable and accurate flow measurement, it is very important that the flow meter is installed correctly in the pipe system;

(2)Flow meter need to be installed on horizontal pipeline.

(3)The inner diameter of the flow meter need to be as same as inner diameter of pipeline, and the axis of the flow meter should be concentric with the axis of the pipeline during installation;

(4)Recommend to install indoors. If need to install outdoors, please make good protection from direct sunlight and rain;

(5)In order to ensure the normal use of the medium is not affected when the flow meter is overhauled, a shut-off valve should be installed on the upstream and downstream of the flow meter. A bypass pipeline should be provided.

(6)The flow control valve must be installed downstream of the flow meter, and the upstream valve must be fully open when the flow meter is used.

Gas Turbine Flow Meter Maintenance:

(1)Gas turbine flow meter need to do oil filling operation regularly to ensure bearings work smoothly.

(2)There’s oil filling operation indication on each Q&T gas turbine flow meter’s body. Follow the indication to do oil filling regularly is fine.
