Please note that the following installation conditions must be obeyed:
Pressure Requirement: MAP16.
Environmental Class: E1, M1
Installation requirement: There must be a distance of minimum 25 cm between signal
cables and other installations
If medium temperature is below 10
°
C or above 90
°
C in flow sensor, It
’
s recommended
that the calculator be wall-mounted.
Note: Seal or any safety marks on the meter must not be damaged or removed, and doing so
will void the warranty and calibration of the meter.
2. Technical Specification
2.1 Flow Sensor
The flow sensor is a device used to measure the velocity of flow by using the principle of
ultrasound. It can measure the average velocity along the path of an emitted beam of
ultrasound by averaging the difference in measured transit time between the pulses of
ultrasound propagating into and against the direction of the flow. The flow measurement is
based on an acoustic wave time of flight principle. The flow meter body is equipped with 2
ultrasonic transducers facing 2 acoustic reflectors.
