Lanry’s Advantages
1. From the outside, you can see our products’ quality. Most of the product parts are imported from USA or Europe. You’ll see Lemo connection(TF1100-EH &EP) and Pelican case(TF1100-EH&CH&EP), Allied enclosure(TF1100-EC). The sensitiveness of our product is better. The act...Read more -
Old pipe with heavy scale inside, no signal or poor signal detected: how can it be resolved?
Check if the pipe is full of fluid. Try the Z method for transducer installation （If the pipe is too close to a wall, or it is necessary to install the transducers on a vertical or inclined pipe with flow upwards instead of on a horizontal pipe). Carefully select a good pipe section and fully cl...Read more -
Method of Estimating Sound Speed of a Certain Fluid
Sound speed of measured fluid is required when using TF1100 series transit-time ultrasonic flow meters. This instruction is used to estimate the sound speed of a certain fluid that the meter system doesn’t tell its sound speed and you have to estimate it. Pls follow the steps bellow for TF1100 s...Read more -
How to Get Signal for Transit- time Flowmeter When No Pipeline
When user is in no pipeline environment and wants to test our Transit- time Flowmeter, user can operate as follow steps: 1. Connect transducers to transmitter. 2. Menu Setup Note: No matter what kind of transducer customers bought, the menu setup of transmitter fol...Read more -
What are the advantages of Ultrasonic water meter in comparison with Mechanical water meter?
A. Structure comparison, ultrasonic water meter without clogging. Ultrasonic water meter DN15 – DN300, reflect hydrodynamic structure, no installation requirements of straight pipe. Mechanical water...Read more -
What is requirement for straight pipe length when installing a transit-time or Doppler flowmeter?
Ultrasonic flow meters require fully developed flow conditions to ensure the meter will perform as specified. There are two basic types of measuring principles, Doppler and Transit Time. Both do require adhering to basic installation guidelines to minimize errors caused ...Read more -
What is Q1, Q2, Q3, Q4 and R for ultrasonic water meter
Q1 Minimum flow rate Q2 Transitional flow rate Q3 Permanent flow rate (working flow) Q4 Overload flow rate Make sure that the maximum flow that will pass through the meter never exceeds Q3. Most water meters have a minimum flow (Q1), below which they cannot provide an accurate reading. If ...Read more -

The principle and application of transit-time ultrasonic flow meter?
A transit-time difference type ultrasonic flowmeter is measured using A pair of transducers (sensors A and B in the figure below), which alternately (or simultaneously) transmit and receive ultrasonic waves. The signal travels faster upstream than upstream in the fluid, ...Read more -
What is difference between reading accuracy and FS accuracy of the flow meter?
The reading accuracy of the flowmeter is the maximum allowable value of the relative error of the instrument, while the full scale accuracy is the maximum allowable value of the reference error of the instrument. For example, the full range of the flowmeter is 100m3/h, when the actual flow is 10...Read more
