ROCKWIN is exclusive distributor in India for EnergoflowAG, Swiss company for Ultrasonic Liquid Flow Meters and Inline type Gas Flowmeters

The Energoflow LF series of liquid flow meters is designed to perfection for reliable and accurate measurement of liquid flow in filled pipelines using the pulse-time method. The flow meters of the series are manufactured in various versions – in-line sections, inserted sensors installation and clamp-on type. ENERGOFLOW LF with clamp-on sensors, inserted sensors and in-line sections are designed for use in field conditions e.g. potable, technical or river water, heat-transfer agent, solutions of alkalis and acids etc. Battery operated version of the single channel inline version of the device with AMR feature is also available.
The portable flow meter ENERGOFLOW LF 2P2 with clamp-on sensors is designed for use in field conditions for monitoring and measurement of flow of liquids eg. water, oil and oil products, industrial chemicals, solvents, etc. in fully filled pipelines. The set comes in a handy, easy to carry durable case and can be used for
:: Single channel (accuracy ± 1.5%) and twin channel (accuracy ± 1%) flow measurements on a single pipeline
:: Real-time comparison or summation of flows in two adjacent pipelines (single channel mode per pipeline)
Size: DN50 – DN3200
Flow Velocity range: 0.10 m/s to 10 m/s
Accuracy: ± 1.5% of flow (Standard)
± 1.0% of flow (Twin Channel)

Four channel ultrasonic gas flow meter Energoflow GFE 404 is a MID/OIML certified specially designed measurement device for applications where very high accuracy is required, e.g. for custody transfer measurement of natural gas. The standard version provides a typical accuracy of 0.5%, flow meters with an accuracy of 0.2% can be supplied after HP calibration on natural gas. The flow meters provide accurate and reliable measurement of the gas flow rate in the pipeline in both directions.

Size: DN100 – DN400
Flow range: 4 m3/hr - 16000 m3/hr
Accuracy: ± 0.5% of flow (Standard)
± 0.25% of flow (Optional)

Ultrasonic Gas Flowmeter GFE-202
Energoflow GFE202 is two channel transit time type ultrasonic gas flow meters designed for natural gas measurement.
Size: DN50 – DN500
Flow range: 1 m3/hr - 10000 m3/hr
Accuracy: ± 1.0 % of flow (Standard)
± 0.5 % of flow (Optional)
