Tofting TF100W

Welcome to use new generation transit-time ultrasonic flowmeter

The TF-100W ultrasonic flowmeter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation.

  • Linearity: 0.5%
  • Repeatability: 0.2%
  • Accuracy:±1%
  • Easy to operate.
  • Several type transducers for selection
  • measuring pipe size is from DN15mm to DN6000mm
  • Adopt low voltage, multipulse technology to improve accuracy
  • useful life and reliability
Applications examples :
  • Water (hot water, chilled water, city water, sea water, waste water, etc.)
  • Sewage with small particle content
  • Oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.)
  • Chemicals (alcohol, acids, etc.)
  • Plant effluent
  • Beverage, liquid,food
  • Ultra pure liquid

Tofting TF100W Energy

ENERGY MEASUREMENT ON PIPE SYSTEMS
If you have a flow and temperature sensor mounted on a system, it is possible to calculate how much energy that is used.
With this solution from Tofting both is possible in one easy to use unit.
A possibility of transport data via RS-232/RS-485 makes it possible to secure all measured data in another unit, such as a PC

Utrasonic Flow measurement principle

The TF-100W transit-time flowmeter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-method where the sound transverses the pipe twice, or W-method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This selection of the mounting method depends on pipe and liquid characteristics. The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pipe, show as follows:

måleprincip1 måleprincip2

Where:

θ is the include angle to the flow direction

M is the travel times of the ultrasonic beam

D is the pipe diameter

Tup is the time for the beam from upstream transducer to the downstream one

Tdown is the time for the beam from downstream transducer to the upstream one

ΔT = Tup –Tdown
