Welcome to use new generation transit-time ultrasonic flow meter, please read the user manual carefully before using. The wall-mount ultrasonic flow meter is designed to be installed in a fixed location for long-term flow measurement.

الميزات

◆ Linearity: 0.5%, Repeatability: 0.2%, Accuracy:±1%

◆ IP67 water & Dust resistant

◆ Several type transducers for selection, measuring pipe size is from DN15mm to DN6000mm

◆ Adopt low voltage, multi-pulse technology to improve accuracy, useful life and reliability.

◆ Powerful Recording Function, record the totalizer data of the last 64 days/64 monthes/5 years.

◆ Three type installation method : wall mounted , DIN-Rain mounted , explosion-proof box mounted

Typical application

The wall-mounting flow meter can be applied to a wide range of pipe flow measurements. Applicable liquids include pure liquids as well as liquid with small quantity of tiny particles.

Examples are:

★ Water (hot water, chilled water, city water, sea water, waste water, etc.);

★ Sewage with small particle content;

★ Oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.);

★ Chemicals (alcohol, acids, etc.);

★ Plant effluent;

★ Beverage, liquid food;

★ Ultra-pure liquids;

★ Solvents and other liquids
