What features are added to the 6537 sensor compared with the previous version 6526?
For the new version meter, we update many functions. 1. velocity range: from 0.02-4.5m/s to 0.02-12m/s 2. level range: from 0-5m to 0-10m. 3. level measure: principle from only pressure to both ultrasonic and pressure measure. 4. new function: conductivity measure. 5. fr...Read more -
How to choose a suitable location of partially filled pipe?
A typical installation is in a pipe or culvert with diameters between 150mm and 2000 mm. The Ultraflow QSD 6537 should be located near the downstream end of a straight and clean culvert, where non-turbulent flow conditions are maximised. The mounting should ensure the unit sits right on the botto...Read more -
What is the main function of QSD6537 sensor ?
Ultraflow QSD 6537 measures: 1. Flow velocity 2. Depth (Ultrasonic) 3. Temperature 4. Depth (Pressure) 5. Electrical Conductivity (EC) 6. Tilt ( the angular orientation of the instrument) The Ultraflow QSD 6537 performs data processing and analysis each time a measurement is made. This can inc...Read more -
when the time ratio displays in M91 exceeds the range of 100±3%,(This is just a reference value), user should check:
1) If the pipe parameters are correctly entered. 2) If the actual mounting spacing exactly coincident to M25 value. 3) If the transducers are installed properly in the right directions. 4) If the straight pipe length is enough. 5) If the preparation work has been done as described above. 6) If th...Read more -
If signal strength value Q displayed in M90 is less than 60 ,following methods are recommended to better off:
1) Relocate a better location. 2) Try to polish the outer surface of the pipe ,and use enough coupling compound to increase the signal strength. 3) Adjust the transducer positioning vertically and horizontally; make sure the transducers spacing is the same as M25 value. 4) when the pipe material ...Read more -
How to install clamp on ultrasonic flowmeter?
Because flow sensors are mounted on the external surface of the pipe,so no demand of breacking the pipeline and it just clamped on the pipe wall by transducers mounting rails or S-S belt as below description. 1. Lay on enough couplant on the transducer and put it to the polished area of pipe to ...Read more -
How to choose Installation Position for clamp on Ultrasonic water flowmeter ?
1. Slect the optimum location, ensure enough straight pipe length usually upstream >10D and downstream > 5D (where D is the inner diameter of the pipe.) 2. Avoid welding seam, bumps, rust, etc. Insulating layer must be stripped. Make sure the contact area is smooth and clean. 3. For TF1100 ...Read more -
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 -
