ULTRASONIC LIQUID FLOW METERS

The Energoflow AG LF series of Ultrasonic Liquid Flow Meters are designed to perfection for reliable and accurate measurement of liquid flow in filled pipelines using the pulse-time method. These flowmeters can be used for flow monitoring and measurement of potable, technical or river water, oil, and petroleum products, heat-transfer agent, solutions of alkalis and acids, warmed fuel oil, heavy oil, stable gas condensate, and liquefied petroleum gas, effluents, etc. at pressures up to 250 bar. A special version capable of working at fluid pressures up to 400 bar is available for applications like measurement of stratal water from oil wells.

The  Ultrasonic Liquid Flow Meters of the series are manufactured in various versions for application over a vast range of process conditions :

• for pipelines from DN25 up-to DN7000
• for flow speeds as low as 0.1 m/s and as high as 10 m/s
• for ambient temperatures as low as -65 deg C and as high as +70 deg C and at 100% humidity
• for liquid temperatures in the range of -20 deg up-to 150 deg C
• in hazardous areas and hard to access locations
• for clamp-on installation, the process pressure is not a consideration, inline versions are available for liquid pressures as high as 400 bar
• for fluids with a considerable amount of suspended solid particles and bubbles (up-to 5% by volume)

The major advantages of the Energoflow AG LF series Ultrasonic Liquid Flow Meters are:

1. No obstruction to the flow and zero pressure loss
2. No moving parts and no mechanical wear or tear
3. Easy installation and simplicity of use
4. Easy integration into all kinds of process management systems
5. High accuracy, large turn-down ratio, reliable measurement and fast reaction to changes in process conditions

Ultrasonic Flow Meters are designed for single-channel and two-channels( four channels under special order). Each channel can be used independently to account for liquid in different pipelines.

ADVANTAGES :

• Simplicity and reliability in the operation;
• Wide range of the measurements of volumetric flow rate (1:150);
• The created archives contained hourly data for past 1024 hours (more than 42 days);
• Adjustment of a flow meter in the complete set with in-line section is carried out on manufacturer;
• There is no contraction inside the in-line section; therefore flow meter does not create the resistance to the flow of liquid and does not introduce disturbances into the flow;
• Automatic adjusting of the signal level;
• A flow meter is equipped with pulse-frequency output, analog output (on order), and interface RS-232;
• The flowmeter with the autonomous power supply works up to 4 years without the replacement of battery;
• A flow meter can be easily integrated into automated SCADA systems and existing control systems;
• The interval between verification - 2 years.
