Handheld Ultrasonic Flow Meter Overview

The Handheld Ultrasonic Flow Meter QTFM realizes non-contact measurement of liquid flow, simply install the sensor on the outer wall of the pipeline to complete the flow measurement. The instrument has characteristics of being small-sized, making it convenient carrying and it gives out an accurate measurement.
Handheld Ultrasonic Flowmeter Principle Working: The time-transit measurement principle is adopted, the signal transmitted by one flow meter transducer passes through the pipe wall, the medium, and the other side pipe wall, and is received by another flow meter transducer. At the same time, the second transducer also transmits the signal received by the first transducer. With the influence of the medium flow rate, there is a time difference, and then the flow value Q can be obtained.

Handheld Ultrasonic Flow Meter Applications

This flow meter is widely used in tap water, heating, water conservancy, metallurgy chemical, machinery, energy, and other industries. It can be used for production monitoring, flow verification, temporary detection, flow inspection, water meter balance debugging, heating network balance debugging,energy-saving monitoring, and it is a necessary tool and meter for timely flow detection.

Variable Area Flowmeter 335 Overview

The Variable Area Flowmeter 335 from GF Piping Systems are radially installed, dismountable meters for measuring the flow rate in industrial piping system constructions. The measuring principle is advanced and efficient. The measurement ranges, which are tailored to our customers‘ needs, and the range of materials available for the tubes and screwed fittings, allow the flow meters to be used for a wide range of applications and a great variety of media.

Function
If a medium flows upwards through the vertically mounted measuring tube at a sufficient flow velocity, the float is raised to the point at which a state of equilibrium sets in between the lifting force of the medium and the weight of the float. As the mean flow velocity is proportional to the quantity flowing through per unit of time, this state of equilibrium corresponds to the measurement of the current flow volume.

Variable Area Flowmeter 335 Features
- Easy and cost-effective measurement principle.
- No additional energy required for the operation.
- Easy reading of the measured value.
- Available scale range from 50 l/h up to 60 000 l/h.
- Printed double scale for water in percent and l/h.
- Special scales for liquid and gaseous media can be attached.
- Wide range of materials.
- Break-proof and corrosion-resistant.
- Large dimensions with guiding rod (PVDF-coated).

Insertion Magmeter Flow Sensor 2551

The Georg Fischer 2551 Magmeter is an insertion magnetic flow sensor that features no moving parts, available in corrosion-resistant materials to provide long-term reliability with minimal maintenance costs. Material options include PP with stainless steel, PVDF with stainless steel, PVDF with Hastelloy-C, or PVDF with Titanium. Utilizing the comprehensive line of Georg Fischer installation fittings, sensor alignment and insertion depth is automatic. These versatile, simple-to-install sensors deliver accurate flow measurement over a wide dynamic range in pipe sizes ranging from DN15 to DN900 (½ to 36 inches), satisfying the requirements of many applications.

Georg Fischer 2551 Magmeters offer many output options of frequency/digital (S3L) or 4 to 20 mA which are available on both the blind and display versions. The frequency or digital (S3L) sensor output can be used with Georg Fischer's extensive line of flow instruments while the 4 to 20 mA output can be used for a direct input to PLCs, chart recorders, etc. Both the 4 to 20 mA output and digital (S3L) sensor interface is available for long distance signal transmission. An additional benefit is the empty pipe detection which features a zero flow output when the sensors are not completely wetted. Also, the frequency output is bi-directional while the 4 to 20 mA output can be set for uni- or bi-directional flow using the display or the 3-0250 USB to Digital (S3L) Configuration / Diagnostic set-up tool which connects to PCs for programming capabilities.

In addition the display version of the 2551 Magmeter is available with relays and features permanent and re-settable total values which can be seen on the display. Also, the display contains multi-languages with English, Spanish, German, French, Italian and Portuguese menu options.

Magmeter flow sensor features:
