Portable Ultrasonic Liquid Flow Meter Energoflow LF-2P2

Portable Ultrasonic Liquid Flow Meter Energoflow LF-2P2

Overview

The Portable Ultrasonic 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, petroleum and petroleum 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 0.5%....1% ) flow measurements on a single pipeline
  • real-time comparison or summation of flows in two adjacent pipelines (single channel mode per pipeline)
Thus the set is a boon for repair teams and field engineers. The built-in digital oscilloscope facility and inline calibration function make installation and commissioning very fast, simple and easy.

The Portable Ultrasonic Liquid Flow Meter can also be used as a full-fledged stand alone liquid flow meter for in-site installations in remote places.

The complete set comprises of the following:
  1. LF-2P2 – Electronic unit (twin channel) with LCD display and keyboard
  2. Electro-acoustic transducer
  3. Removable plates (for clamp-on installation)
  4. Power unit / Battery charger 5V, 1А
  5. Thickness gauge
  6. Water-resistant grease
  7. Accumulator charger
  8. Tapping hammer with screwdriver
  9. Measuring roulette
  10. Standards strip for calibration of thickness gauge
  11. Connecting cables for transducers with connectors, 2 x 10 m
  12. Carrying case
  13. Accessories for installation on pipes (chains and clamps)

Manufacturer's warranty certificate, instruction manual and software CD with cable (for connecting the electronic unit to PC for data transfer and configuration) are provided with each set.
