FAQ
Q: What is the operating principle of the D118 Ultrasonic Flowmeter?
A:The D118 Ultrasonic Flowmeter operates based on the transit-time principle.
Q: How do I set the pipe diameter in the D118 Ultrasonic Flowmeter?
A:To set the pipe diameter, you need to enter the 'Pipe Outer Diameter' window (M11) and input the diameter value. For insertion transducers, you should enter the pipe inner diameter.
Q: What are the different transducer mounting methods available for the D118 series?
A:The D118 series supports three transducer mounting methods: V method, Z method, and N method. The V method is standard and suitable for most applications, the Z method is used for larger diameter pipes or where signal strength is a concern, and the N method is used for smaller diameter pipes.
Q: How do I perform zero calibration on the D118 Ultrasonic Flowmeter?
A:Zero calibration is performed by pressing the 'Set Zero' option in the menu (M42).
Q: How can I check the signal strength and quality of the D118 Ultrasonic Flowmeter?
A:You can check the signal strength and quality by accessing the 'Signal Strength and Quality' window (M90). The signal strength is indicated by a number from 00.0 (no signal) to 99.9 (maximum signal strength), and the quality (Q value) is indicated by a number from 00 (minimum signal) to 99 (maximum signal). Proper installation and adjustment of the transducers are necessary to achieve optimal signal readings.
