Flange clamp vortex flowmeter

The LUGB series flange clamp type vortex flowmeter is a commonly used structural form, and its meter body does not have a connecting flange. When connecting to a pipeline, the flowmeter is clamped between two dedicated flanges and then tightened with bolts. Its characteristics are small size and simple and compact structure. At the same time, dedicated flanges and fastening bolts are provided, so the installation cost is low and the installation is very convenient.

Product Characteristics

Easy installation and very convenient maintenance;

The structure is simple and firm, with no movable parts, making it highly reliable for long-term operation;

Wide range, with a range ratio of up to 1:15;

Low pressure loss, low operating costs, and more energy-saving significance;

Wide application range, liquid, gas, and vapor can be measured;

The calibration cycle is long, usually two years;

Within a certain Reynolds number range, the output signal is not affected by the physical properties and composition changes of the measured medium, and the instrument coefficient is only related to the shape and size of the vortex generator. After replacing accessories, it is generally not necessary to recalibrate the instrument coefficient;

It can be displayed on-site, transmitted remotely, and connected to a computer control system;

The detection probe does not directly contact the tested medium, resulting in more stable performance.
