Turbine Fuel Flow Meter
Turbine fuel flow meter is a temperature and pressure compensation function of the speed of flow measurement apparatus, belongs to the speed of a flow meter, its working principle: the power of the flowing fluid drives the turbine blade rotation, its rotational speed and volume flow rate is approximately proportional to the volume of fluid through the flow meter is based on the number of rotations of the turbine impeller as a benchmark. Turbine fuel flow meter due to its high measurement accuracy, repeatability and stability, wide range, rapid response to changes in flow, anti-interference ability, signal transmission and other characteristics.
Overview
Maintenance knowledge:
Before the sensor is installed, use the mouth to blow or hand dial the impeller, make it rotate quickly to observe whether there is a display, when there is a display and then install the sensor. If there is no display, should check the relevant parts, troubleshooting.
When used, the measured medium should be kept clean, free of impurities such as fibers and particles.
Turbine fuel flow meter in the beginning of use, the sensor should be slowly filled with media, and then open the outlet valve (the valve should be installed at the back end of the flowmeter), the sensor is strictly prohibited in the absence of media state by the impact of high-speed fluid.
Turbine fuel flow meter maintenance cycle is generally half a year. Overhaul and cleaning, please note that do not damage the measuring chamber parts, especially the impeller. When assembling, please look after the positional relationship between the guide parts and the impeller.
When the tTurbine fuel flow meter is not used, the internal media should be cleaned, blown dry and at both ends of the sensor plus a protective sleeve to prevent dust and dirt from entering, and then placed in a dry place to save.
Turbine fuel flow meter with the filter should be cleaned regularly, when not in use should be cleaned of the internal media, the same as the sensor, plus dust cover, placed in a dry place to save.
