What is the difference between two-wire and three-wire ultrasonic level meter ?
For Two-wire ultrasonic level meter, its power supply (24VDC) and signal output ( 4-20mA ) share a loop, only two lines can be used, this is the standard transmitter form, the deficiency is that the transmission power is relatively slightly weak. Three-wire ultrasonic level meter is actually fo...Read more -
Why does Lanry flow meter show low signal value?
1. Check the pipe is full or not full water pipe,if empty or partially filled pipe,flow meter will display a bad signal; ( For TF1100 and DF61serial transit time flow meter ) 2. Check the pipe measured if it is used enough coupling paste when mounting the sensors,if air is between the sensor surf...Read more -
What factors result in bad flow measurement for our transit time ultrasonic flow meter ?
1. Old pipe and server scaling for pipeline. 2. The pipe material is pyknotic and symmetrical,and other materials that is bad acoustical conductivity; 3. The surface of pipe wall have coating like paint; 4. The application is not full water pipe; 5. The inner of pipe is with a lot of air bubbles ...Read more -
What is the accuracy of Lanry flow meters ?
For volumetric flow measurement, The accuracy of transit time ultrasonic liquid flow meter is up to 1%. ( Full filled pipe in pure water and little dirty water ) The accuracy of clamp-on dual channels transit-time ultrasonic liquid flow meter is up to 0.5%. (Full filled pipe in pure water and lit...Read more -
