TF1100-EC clamp on ultrasonic flowmeter COMMUNICATIONS PROTOCOL
The TF1100 has communication protocol. Its hardware directly supports a modem, a composition of flow data monitoring system that is economical, reliable and based on telephone line transmission. It can also be connected to a RS-485 or RS232C connectors based on jumpers on circuit board for user’s...Read more -
DOF6000 open channel flow meter—Instantaneous Versus “Averaged” Velocity
from scan to scan at some sites. Because Ultraflow QSD 6537 is very sensitive to variations in velocities, you are able to see the natural velocity changes in the channel. Although the discharge in a channel may be reasonably constant for a period of time, the velocity distribution is always chan...Read more -

TRANSDUCER CABLES
After the transducers A and B inserting into the pipe, the sensor cables should be routed to the transmitter location. Verify that the supplied cable length is sufficient to meet the installation requirements. While transducer cable extension is not generally recommended, if additional transducer...Read more -
TRANSDUCER INSTALLATION PROCEDURES
Locate the reference mounting positions of 3 and 9 o’clock (180° symmetrically) as shown in Fig 3.1. Two transducers called A and B transducer, A is transmitting transducer and B is receiving transducer, they must be installed 180° symmetrically in order to have a more accurate measuring, shown ...Read more -
