Technical Data
Flange ultraosnic flow meter is one kind of economy liquid flow meter which mainly measure various of pure liquid,such as:Clean water,Sea water,Dringking water,River water,Alcohol etc.
And it is suitable for continuously measuring flow and heat of clean and uniform liquids without large concentration suspended particles or gases industrial environment.
Accuracy better than ±1.0%
High reliability, high performance, low price
Bi-directional flow measurement
No moving parts, no wear, no pressure loss,Maintenance-free 
Measuring conductivity liquid and Non-conductivity liquid
Display instantaneous flow,Total flow,Heat,Positive flow,Negative flow
High-precision machined pipe sections, the sensor is installed before leaving the factory to ensure high measurement accuracy
Inline ultrasonic flow meter could connect temperature sensor to become one calorimeter and widely be used in Food industry, Oil & Gas industry, Chemical industry,Water treatment industry, Trade settlement,Power industry

Integral Display Flange Ultrasonic Flow Meter Installation Requirement
Generally, the following principles should be followed:
  • To select a pipe section filled with fluid, such as a vertical part of the pipeline or a horizontal pipe section filled with fluid.
  • The measuring point should be 10 times the diameter from the upstream and the straight pipe section within 5 times the diameter from the downstream, and the distance from the valve outlet should be as far as possible.
  • Ensure the temperature at the measuring point is within the working range. 
  • Fully consider the fouling condition of the inner wall of the pipe, and try to select a non-scaling pipe section for measurement. When it cannot be satisfied, fouling should be considered as a lining for better measurement accuracy. 
  • Select pipe sections with uniform and dense pipes that are easy for ultrasonic transmission.
Please refer to the two examples on the right for the selection of measuring points.
