Water treatment application for DOF6000 serial area velocity flow meter
Application Background Water quality measurements are performed for water in streams, rivers, lakes and in groundwater systems. There are different parameters that can be measured and used as indicators of water quality, for example electro conductivity (EC), acidity or alkalinity of a solution (...Read more -
What is the main application for ultrasonic flowmeter ?
The ultrasonic flowmeter, just like the electromagnetic flowmeter, it belongs to the non-intrusive flowmeter because there is no obstruction. It is a kind of flowmeter suitable for solving the aporia of flow measurement, especially has prominent advantages in the flow measurement for large diamet...Read more -

What historical data is stored in the ultrasonic water meter? How to check?
The historical data stored in the ultrasonic water meter includes the hourly positive and negative accumulations for the last 7 days, the daily positive and negative accumulations for the last 2 months, and the monthly positive and negative accumulations for the last 32 months. These data are st...Read more -
Why is the CL output abnormal?
Check to see if the desired current output mode is set in Window M54. Check to see if the maximum and minimum current values are set properly in Windows M55 and M56.Re-calibrate CL and verify it in Window M53.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 cle...Read more -
New pipe, high quality material, and all installation requirements met: why still no signal detected?
Check pipe parameter settings, installation method and wiring connections. Confirm if the coupling compound is applied adequately, the pipe is full of liquid, transducer spacing agrees with the screen readings and the transducers are installed in the right direction.Read more -
What is the Measuring principle: Time-of-flight method for UOL open channel flow meter?
The probe is mounted on the top of the flume, and ultrasonic pulse is transmitted by the probe to the surface of the monitored material. There, they are reflected back and received by the pro be. The host measures the time t between pulse transmission and reception. The host uses the time t (and ...Read more -
Hints for probe mounting ( UOL open channel flow meter )
1. The probe can be supplied as standard or with a screw nut or with an ordered flange. 2. For applications requiring chemical compatibility the probe is available fully enclosed in PTFE. 3. The use of metallic fittings or flanges is not recommended. 4. For exposed or sunny locations a protect...Read more -
Steps to the installation of the transducers of TF1100-CH flow meter
(1) Locate an optimum position where the straight pipe length is sufficient, and where pipes are in a favorable condition, e.g., newer pipes with no rust and ease of operation. (2) Clea n any dust and rust. For a better result, polishing the pipe with a sander is strongly recommended. (3) Apply a...Read more
