Ultrasonic Water Flow Meter, Wall Mounted

The wall mounted ultrasonic flow meter is designed to measure the flow of liquids in various closed pipes, measuring range from DN25 to DN600 mm, with instantaneous and totalised values displayed in real time, compatible with 4-20mA/OTC pulses, RS485 communication, etc. The optimised intelligent signal adaption allows the user to use the meter without any circuit adjustments, just as easy as using a multimeter.

Specification

Transducer Selection

Feature

1. Host Upgrade: 2-in-1 volume is more compact, easier to use and carry.
2. Probe Upgrade: Transmitter power is strengthened, only one kind of probe is needed, easy to realize DN25-1200 caliber pipeline flow measurement Protection level is upgraded to IP68, which can resist water immersion.
3. Signal Upgrade: Standard 4-20mA output, support standard 485 communication standard, 10-36V instrument wide voltage supply.
4. Installation Upgrade: Alternative to the traditional pipeline installation flowmeter, without the need to stop the flow of broken pipe, pipe wall a paste to easily realize the flow measurement.

Transducer Installation

1. Choosing right installation position

• The pipeline where the transducer is installed must have a long enough straight pipe section, of course, the longer the better, generally 10 times the pipe diameter upstream, 5 times the pipe diameter downstream, and 30 times the pipe diameter from the pump port. At the same time, ensure that the liquid in this section must be full.
• Make sure that the temperature range of the pipe under test is within the applicable range of the sensor, usually at room temperature.
• Take the corrosion or scaling of the pipeline into consideration. It is better to choose a newer pipeline for the measurement. If it is not available, subtract the corrosion from the pipe wall thickness or consider scaling as the pipe lining.

2. Transducer installation method

• Z-installation method: generally suitable for the pipes above DN100mm

• V-installation method: generally suitable for the DN20-300mm pipes

• W-installation method: usually used for pipes of DN10- 100mm pipes

* The installation distance is shown after entering the pipe parameters into the ultrasonic flow meter.
