Energoflow AG LF 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.

| Energoflow AG LF Ultrasonic Liquid Flow Meters |
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.
Energoflow AG LF 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)
Advantages :
- No obstruction to the flow and zero pressure loss
- No moving parts and no mechanical wear or tear
- Easy installation and simplicity of use
- Easy integration into all kinds of process management systems
- 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.
