Transit Time Meter Basic Theory
Measurements are made by sending bursts of signals through a pipe . The measurement of flow is based on the principle that sound waves travelling in the direction of flow of the fluid require less time than when travelling in the opposite direction. At zero velocity , the transit time or delta T is zero. If we know the diameter of the pipe
Doppler Flowmeter Basic Theory
Doppler ultrasonic flowmeters operate on the Doppler shift principal , whereby the transmitted frequency is altered linearly by being reflected from particles and bubbles in the fluid. The net result is a frequency shift between transmitter and receiver frequencies that can be directly related to the flow velocity. If the pipe internal diameter is known, the volumetric flow rate can be calculated. Doppler meters require a minimum amount of solid particles or air in the line to achieve measurements.
Product Demonstrations
EESIFLO Portalok 7s Clamp on cross correlation time of flight ultrasonic Flow Meter for Most Liquid Applications in and outdoors.
This is no ordinary ultrasonic flow meter because it has been designed with
the operator in mind.
Flow logging ability, precision sensors , water resistant case, connectors and sensors along with years of investment in its development led by customer
feedback. Good battery life and trouble free flow measurement.
EESIFLO Dual Channel Meter for high speed measurements and energy (BTU MW/HR) instantaneous calculations in HVAC systems or extremely large pipes.
Designed for operators who may have challenges that other clamp on
Ultrasonic flow meters fail to meet. Lots of options for extremely small
Pipes or tubes or large pipes . This meter has been set apart from all other ultrasonic flow meter models due to its uncanny performance ability.
EESIFLO Hand Held Doppler Flow Meter for raw sewage and applications with High solids content or bubble content. A low cost but reliable option
for certain applications where bubbles or solids are so high that an attenuation problem occurs with other technologies. A choice of volume measurement in either metric or imperial units.
