Product catalog summary
Overview: The LTFC-300 is a high-performance velocity flowmeter designed for fixed installations in open channels, part-filled pipes, and river applications. It utilizes the area-velocity method for fluid flow measurement, employing a submerged ultrasonic sensor to determine flow velocity and liquid level.
Flow Measurement Principle: The device uses ultrasound to measure flow velocity by detecting frequency shifts caused by bubbles and particles in the liquid. The flow rate is calculated by multiplying the flow velocity by the cross-sectional area, which is derived from liquid level measurements.
Specifications:
  • Power Supply: 19 to 50 Vdc, 30 VA consumption
  • Dimensions: 166x161x103 mm, IP 65 protection
  • Operating Temperature: 0 to 50ºC
  • Display: 3.5-inch TFT, touch screen, multiple display modes
  • Communication: RS485 MODBUS, USB, optional Ethernet
  • Inputs/Outputs: 1 or 2 measuring channels, 2 analog outputs, optional alarms
Benefits and Features:
  • Easy installation without weirs or flumes
  • Bi-directional velocity measurement
  • High sensitivity for clean water applications
  • Real-time processing and smart power saving
  • Distance capability up to 500 m from sensor to unit
Technical Data:
  • Velocity Measurement: Submerged ultrasonic sensor, -5 m/s to 5 m/s range
  • Resolution: Better than 1 mm/s
  • Environmental Protection: IP 68 for sensor, IP 67 for connection box
Level Measurement Options:
  • Submersible Pressure Transmitter: Ranges from 1 to 10 m.w.g, accuracy 0.5% FSO
  • Ultrasonic Level Transmitter: Ranges from 0.1 to 10 meters, accuracy 0.3% FSO
Applications: Suitable for effluent monitoring, wastewater treatment, industrial flow measurement, irrigation channels, river/stream flow measurement, water distribution, and sewer flow measurement.

Flow Measurement Principle The LTFC-300 uses the area-velocity method to give a continuous or time sample measurement offluid flow. The unit uses a streamlined probe that operates immersed in the flowing liquid. The velocity probe transmits ultrasound into the liquid to create a zone of inspection. Bubbles and solid particles carried through this zone by the flow, even when present in only minute quantities, reflect ultrasound back to the probe. Only high quality signals containing verified velocity information isused, thereby ensuring measurement integrity. This measured frequency shift in the...
