FU external clamp ultrasonic flowmeter-Fornitore globale

1st Floor, Building 2, No. 89 Huguang East Road, Meilian Industrial Park, Minhang District, Shanghai (201108)

Principle, structure

An instrument that measures volumetric flow by detecting the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse). The external mounted ultrasonic flowmeter consists of a host and an external mounted sensor. By simply attaching the sensor to the surface of the pipeline, various liquid flow measurements can be completed. Unlike other types of flowmeters, it does not require pipe or flow interruption and is easy to install.

application

Widely used in industries such as tap water, heating, water conservancy, metallurgy, chemical industry, machinery, energy, etc., it can be used for production monitoring, water balance debugging, heat network balance debugging, and energy conservation monitoring.

characteristic

The optimal choice for new large-scale pipelines without real flow verification parameters

● Measurable non-conductive liquids

The measurement of DN15~DN6000mm pipelines can be completed by a set of hosts and several pairs of sensors in combination

● No flow obstruction measurement, no pipeline pressure loss

● Automatically remember the cumulative flow rate of the previous 512 days, 128 months, and 10 years, automatically remember the power on/off time and flow rate of the first 64 times, and automatically remember whether the working status of the flowmeter is normal for the first 32 days

● Support heat measurement, equipped with temperature sensors, can achieve heat measurement.

● Supports SD card storage for data storage.

About coupling agents

Short term measurements can be made using butter (with good acoustic properties) or lipids such as Vaseline.

Long term measurement can be done with silicone grease and silicone gel

High temperature measurement can be carried out using silicone grease or high-temperature coupling agents.

About installation method

External clamp sensors have V-shaped and Z-shaped installation methods.

Normally, when installing pipelines with an inner diameter ranging from DN15 to DN40, the V-shaped installation method is preferred. When the signal strength of the V-shaped installation method is poor, it can be replaced with the Z-shaped installation method.

When installing pipelines with an inner diameter above DN40, the Z-type installation method can be prioritized. When the pipeline material is cast iron, the Z-type installation method should be preferred.

V-shaped installation method

Align a pair of sensors horizontally during installation
