Portable Clamp-On Ultrasonic Flow Meter for Water

Features

• Convenient use, fast testing & less maintenance. The non invasive ultrasonic flow meter can measure the liquid flow rate inside the pipe without disassembling the pipe and pressure loss
• Applicable for various pure liquids including water, tapwater, seawater, beers, lubricants, gasoline, cooking oil, etc.
• Compatible with various material pipes like cast iron pipe, galvanized pipe, stainless steel pipe, PVC pipe, aluminum pipe, etc. The ultrasonic flow meter with the proper clamp-on transducer does well in these applications.
• Measuring diameter covers a wide range of DN32-DN6000, suitable for all kinds of industrial site installation and use.
• Big LCD display the instantaneous flow rate and cumulative flow rate at the real time.
• Built-in data logger, the ultrasonic flowmeter can storage 2000 lines of data.
• With RS-232 communication interface, the flow meter can be connected to computer for data collection, user friendly.

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

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