Portable Clamp-On Ultrasonic Flow Meter

ATO manufactured portable ultrasonic flow meter is designed for wide pipe sizes ranging from 32mm to 6000mm in nominal diameter with accuracy ±1% of reading. Big LCD display, built-in large capacity data logger, batteries-powered for long working. With clamp-on installation, the non-invasive flow meter from Chinese supplier is easy to install, convenient to operate, and less maintenance, suitable for virtually all pure liquids like water, gasoline, oils and so on. Wholesale price, high accuracy and good repeatability.

Portable clamp-on ultrasonic flow meter for water

Features:

  • Convenient use, fast testing & less maintenance. The Chinese noninvasive 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 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.

Transducer Installation:

1. Choosing right installation position
Ultrasonic flow meter transducer installing 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
