System Descri ption and Measurement Method

• The OCTAVE’s measurement method is based on an ultrasonic, transit-time, dual-beam sensor which determines the length of time it takes an ultrasonic sound wave to travel the distance between the two sensors located on the meter’s body. The two sensors function as both the sender and the receiver, each one alternating these functions so that the ultrasonic wave travels both with and against the direction of the flow. Since the ultrasonic wave travels slower against the flow than with the flow, the time difference of two waves traveling with and against the flow leads to determining the velocity of the water

• The OCTAVE ultrasonic flow meter is a battery-powered precision flow meter designed for linear, bidirectional flow measurement of water

• Flow measurement values can be transferred through the standard digital or analog output

• The OCTAVE can be set up for a wide range of applications

Notes

• For proper flow measurements, the OCTAVE’s measuring tube should be completely full at all times. Non-wetted sensors show loss of signal. Though this will not cause damage to the meter, it will, however, not measure flow and display zero

• Flow direction: The OCTAVE is a bidirectional flow meter. Note the indicating arrow on the OCTAVE’s display for forward and backward flows

• In case of direct sunlight exposure, it is recommended to keep the lid closed, though no direct damage will occur with the lid open

• Do not expose the OCTAVE to excessive vibration. To avoid vibration, support the pipeline on both side of the meter

• Ambient working temperature: -25 to +55°C

• Water working temperature: 0.1 to +50°C

• To avoid measuring errors due to air in the flow tube, observe the following precautions:

• Since air collects at the highest point of the system, installation of the flowmeter should be at the lowest point

• Always install control valves downstream of the meter in order to avoid cavitation

• ever install the meter on a pump suction side in order to avoid cavitation

10.0

Pipe flanges

• Refer to the standard dimensional drawings for flange spacing, accommodating for the thickness of gaskets

• Install meter in line with the pipe axis. The pipe flange faces must be parallel to each other

• Permissible length deviation: Lmax - Lmin ≤ 0.5

mm ( 0.02” )

mA Module (Analog)

• The current output is a passive 4-20mA.

• 4 mA is always “ 0” (zero) flow and the 20 mA is factory programmable according to the customer requirements.. (If the customer did not specify, the

20 mA will be the maximum flow rate)
