    H battery can work continuously for more than 8 hours without recharge. The NCM-603 also has a built-in data-logger, which allows storage of 2,000 lines of data. The stored information can be downloaded to a PC through its RS232 connection port with software or Windows HyperTerminal software.

  • Page 8: Principle Of Measurement

    1.3 Principle of Measurement The NCM-603 ultrasonic flowmeter is designed to measure the velocity of liquid within a closed conduit. It uses the well-known transit-time technology. The transducers are a non- contacting, clamp-on type. They do not block the flow, thus there is no pressure drop. They are easy to install and remove.

Any user-entered configuration value will be stored in the NVRAM (non-volatile memory), until it is modified by the user. 2.3 Keypad The keypad of the flowmeter has 16+2 keys.

  • Page 15: Menu Windows

    There are three different types of menu windows: (1) Menu windows for number entering, e.g., M11 for setting up the pipe outer diameter. (2) Menu windows for option selection, e.g., M14 for the selection of pipe materials. (3) Results display windows, e.g. window M00 for displaying Velocity, Flow Rate, etc. For number entering windows, the user can directly press the digit keys if the user wants to modify the value.

  • Page 18 Select a relatively new straight pipe line if it is possible. Old pipe tends to have corrosions and depositions, which could affect the results. If you have to work on an old pipe, we recommend you to treat the corrosions and depositions as if they are part of the pipe wall or as part of the liner.

  • Page 19: Transducers Installation

    2.8 Transducers Installation The transducers used by the NCM-603series ultrasonic flow meter are made of piezoelectric crystals both for transmitting and receiving ultrasonic signals through the wall of liquid piping system. The measurement is realized by measuring the traveling time difference of the ultrasonic signals.

It is also called the reflective method. 2.8.3 Z-method Installation Z-method is commonly used when the pipe diameter is between 200mm (8”) and 3,000mm (120”). 2.8.4 W-method Installation W-method is usually used on plastic pipes with a diameter from 20mm (3/4”) to 50mm (2”).

  • Page 21: Installation Checkup

    2.8.5 N-method Installation This method is rarely used. 2.9 Installation Checkup After completion of the transducer installation, the user should check the following items: the receiving signal strength, the signal quality Q value, the delta time (traveling time difference between the upstream and the downstream signals), the estimated liquid sound speed, the transit time ratio, etc.

  • Page 22: Total Transit Time And Delta Time

    2.9.3 Total Transit Time and Delta Time The total transit time (or traveling time) and the delta time are displayed on menu window M93. They are the primary data for the instrument to calculate the flow rate. Therefore, the measured flow rate will vary as the total transit time and delta time vary. The total transit time should remain stable or vary in a very small range.
