  • 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 ...

  • 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 ...

  • 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...

  • 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...

  • 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 ...

  • 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 ...

  • 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 un...

  • Working principle and application of Doppler flow meter

    Doppler ultrasonic flowmeter uses the physics of the Doppler effect, in any liquid flow in the presence of discontinuity will be reflected ultrasonic signal frequency shift (that is, signal phase difference), by measuring the phase difference, the flow rate can be measur...
