How does the transit-time ultrasonic flowmeter measure certain chemical medium ?
When our flow meter measure this chemical liquid,it is necessary to input the sound velocity of this liquid by manual,due to the transmitter of our meter is no option of certain chemical fluids. In general, it is difficult to obtain the sound velocity of special chemical media. In this case,it ne...Read more -
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 -
How to install clamp on type ultrasonic flow meters from Lanry instruments ?
As the ultrasonic sensors are simply clamped on the pipe surface, Lanry ultrasonic flow meters can be installed without no need of breaking into pipelines. The fixing of the clamp-on sensors is using by S-S Belt or transducer mounting rails. In addition,the couplant is applied to the bottom of th...Read more -

Lanry brand Doppler flow measurement liquid can measure the flow rate of dirty liquids with solids or air bubbles,like waste water,ground water,slurry,industrial sewage water, sludge and mining applic...Read more -
The real cases of TF1100-EC clamp on ultrasonic fixed flowmeter
TF1100-EC Clamp on Ultrasonic flowmeter is an instrument of flow measurement that is easy to install. It doesn’t require any damage of the pipe measured. It is ideal for process measurement for many water applications. Clamp on meter is ok to measure the liquid flow that the pipe material i...Read more -
The working principle of ultrasonic water meter smart
A transit time ultrasonic flow meter uses ultrasonic transducers that can both send and receive signal. The ultrasonic signal is transmitted between the transducers through the fluid that pass through the flow meter. The transducers are organized so that the sound velocity will interact with the ...Read more -
The development history of area-velocity flow meter from Lanry
Our area velocity flow meter is a type of flow instruments in open channel and partially filled pipe. Area-Velocity Doppler flowmeter is ok to calculate flow ,flow rate and level measurement for all kinds of fluid (from little dirty to very dirty liquids ) by ultrasonic probe and pressure probe....Read more -
V-Mode and W-Mode Installation of transit time portable handheld flowmeter ultrasonic
1. For TF1100 clamp on flow transducers, place a single bead of couplant, approximately 0.05inch [1.2mm] thick, on the flat face of the transducer. Generally, silicone-based grease is used as an acoustic couplant, but any grease-like substance that is rated not to “flow” at the temperature that t...Read more -
TRANSDUCER SPACING of transit time clamp on ultrasound flowmeter
Transit time ultrasonic clamp-on transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-mode where the sound transverses the pipe two times, W-mode where the sound transverses the pipe four times, or in Z-mode where the ...Read more
