ATF3500 Series
The ATF3500 series is a liquid turbine flowmeter, as fluid flows through turbine rotor and drives it to rotate, the rotating rotor periodically cuts magnetic field line to generate electric pulse signal, which can be transmitted to output or transferred to the meter to display flow rate and totalizer. It features high accuracy, good repeatability, simple structure, low pressure loss, convenient maintenance, etc. It is ideal to measure the volume of low-viscosity liquids in closed pipes, such as tap and demineralised water, fuels, liquefied gases, light fuel oil, solvents, pharmaceutical fluids, food, etc.
AUF761 Series
The AUF761 Series is a fixed-mounted, transit-time ultrasonic Flowmeter. It features factory-mounted transducers that allow it to be flow lab calibrated, reducing or eliminating the random or bias error that can be present in clamp-on style transducer mounting. The meter ensures an accurate, non-invasive measurement of clean homogeneous liquid process, and is widely used in process control and production measurement.
