Page 5: Introduction
1. Introduction 1.1 Preface Welcome to handheld ultrasonic flow meter that has been manufactured with patent technologies and is equipped with more functions and advanced performance than our previous versions. The ultrasonic flow meter has been upgraded based on the previous ultrasonic flow meter which is still the main product line of the company. -
Page 6: Principle Of Measurement
1.3 Principle of Measurement The ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation. The transit time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. -

Page 8: Typical Applications
Transducer cable: RS232 interface cable 1.6 Typical Applications The ultrasonic flow meter can be virtually applied to a wide range of measurements. A variety of liquid applications can be accommodated: ultra-pure liquids, potable water, chemicals, raw sewage, reclaimed water, cooling water, river water, plant effluent, etc. Because the instrument and transducers are non-contacting and have no moving parts, the flow meter can not be affected by system pressure, fouling or wear. -

Page 10: Starting Measurement
2. Starting Measurement 2.1 Built-in Battery The ultrasonic flow meter can operate either from the built-in Ni-H rechargeable battery, which will last over 12 hours of continuous operation when fully recharged, or from an external AC/power supply from the battery charger. The battery charging circuits employ a scheme of constant-current and constant-voltage. -

parameters configured last time by the user or by the initial program. The flow measurement program always operates in the background of the user interface. This means the flow measurement will keep on running regardless of any user menu window browsing or viewing. Only when the user enters new pipe parameters will the flow meter change measurement to the new parameter changes. -
Page 12: Menu Windows
2.4 Menu Windows The user interface of this flow meter comprises about 100 different menu windows that are numbered by M00, M01, M02 … M99. There are 2 methods to enter certain menu window: (1) Direct going/entering. The user can press the MENU key followed by two-digit number keys. - Page 13 2.5 Steps to Configure the Parameters The following parameters need to be configured for a proper measurement: Pipe outer diameter Pipe wall thickness Pipe materials (for non-standard pipe materials*, the sound speed for the material must be configured too) *Standard pipe materials and standard liquids refer to those with the sound parameters that have already been programmed into software of the flow meter, therefore there is no need to configure them Liner material and its sound speed and thickness, if there is any liner.

The first-time users may need some time to get familiar with the operation. However, the user friendly interface of the instrument makes the operation quite easy and simple. Before long, the user will configure the instrument with very little key pressing, since the interface allows the user to go to the desired operation directly without any extra steps. - Page 15 Up s t r e a m Do wn s t r e a m Pi p i n g Co n f i g u r a t i o n Di me n s i o n Di me n s i o n a n d L u p L d n...

Page 16: Transducers Installation
2.7 Transducers Installation The transducers used by the series ultrasonic flow meter are made of piezoelectric crystals ceramic plate; 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. -
Page 17: V-Method Installation
2.7.2 V-method Installation V-method installation is the most widely mode for daily measurement with pipe inner diameters ranging from 15 mm to 400 mm. It is also called reflective mode. 2.7.3 Z-method Installation Z-method is commonly used when the pipe diameter is above 200mm. For insertion transducers, Z method is usually selected and used. -
Page 18: W-Method Installation
2.7.4 W-method Installation W-method is usually used on plastic pipes with a diameter from 15mm to 50mm. 2.7.5 N-method Installation N-method is used for small pipe size. But W-method has more often used than N-method. Thus, N-method is rarely used method in fact. 2.8 Installation Checkup Through the checkup of the installation, one can: check the receiving signal strength, the signal quality Q value, the traveling time difference of the signals, the estimated liquid... -
Page 19: Signal Strength
2.8.1 Signal Strength Signal strength indicates the amplitude of receiving ultrasonic signals by a 3-digit number. [000] means there is no signal detected and [999] refers to the maximum signal strength that can be received. Although the instrument works well if the signal strength ranges from 500 to 999, stronger signal strength should be pursued, because a stronger signal means a better result. -
Page 20: Time
2.8.4 Time Ratio between the Measured Total Transit Time and the Calculated Time This ratio would be used to check the transducer installation. If the pipe parameters are entered correctly and the transducers are installed properly, the value for this ratio should be in the range of 100±3. -

Page 27: How To
4. How To 4.1 How to judge if the instrument works properly Enter into M08, If ‘R’ is displayed on the screen, the instrument is working properly, If 'E' is displayed, the current loop output is over-ranged. Increasing the range setting in M57 will make the 'E' letter disappear. -
Page 28: How To Change Between Units Systems
4.3 How to change between units systems Use menu window M30 for the selection of unit system in English or Metric system. 4.4 How to select a required flow rate unit Use menu window M31 to select the flow unit first and then the timing unit. 4.5 How to use the totalizer multiplier Use window M33 to select a proper totalizer. -

instrument with default values except “instrument factor” and “network identification number” parameter 4.9 How to use the damper The damper acts as a filter for a stable reading. If ‘0’ is entered in window M40, that means there is no damping. A bigger number brings a more stable effect. But bigger damper numbers will prevent the instrument from acting quickly. -
Page 30: How To Use The System Locker
4.13 How to use the system locker The system locker provides a means of preventing inadvertent configuration changes or totalizer resets. When the system is locked, menu window browsing can be done without affecting any change, but any modifications are prohibited. The system can be locked without a password or with a 1 to 4 digit password. -
Page 31: How To Use The Frequency Output
4.15 How to use the Frequency Output There is a Frequency Output in all the series flow meters. This frequency output signal, which represents the flow rate, is intended to connect with other instruments. The Frequency Output is totally user-configurable. Generally, four parameters should be configured for the setups. - Page 32 4.17 How to produce an alarm signal There are 2 types of hardware alarm signals that are available with this instrument. One is the Buzzer, and the other is the OCT output. Both for the Buzzer and OCT output the triggering sources of the event include the following: There is no receiving signal There is poor signal received.

The problems are likely caused by the user who has used the ‘Set Zero’ function on this non-standstill flowing pipe. To solve this problem, use the ‘Reset Zero’ function on menu window M43. The displayed flow rate is much lower or much higher than the actual flow rate in the pipe under normal working conditions.
