Dwyer UFB Series Ultrasonic Flow Transmitter Set

Wiratama Mitra Abadi 01 01.51 flow measurement,

Dwyer UFB Series Ultrasonic Flow Transmitter Set utilizes the transit-time difference for measuring flow rates in pipes non-invasively. This is the permanent model, allowing the user to mount the converter on a surface or pipe.

The easy-to-use Dwyer Ultrasonic Flow Transmitter and lightweight design is intended for mechanical devices using ideally homogeneous liquids that contain no air pockets. The Series UFB comes with a sturdy IP65 rating, protecting it from dust and direct water contact. The Series UFB has 4 to 20 mA and pulse output capabilities.

Converter
Set of Transducers
Ruled Guide Rail
Steel Banding
Banding Clips
Set of Transducer Cables
Set of High Temperature Interface Cables
Ultrasonic Coupling Grease

Principles Of Operation

Two sensors are placed on the exterior of the pipe, and each transmits an ultrasonic pulse through the pipe and fluid to the other. The velocity of the liquid flowing through the pipes causes the pulse to accelerate or decelerate.

The difference in the transit times of the two pulses is used to calculate the flow rate. The use of transit time allows the flowmeter to be unaffected by pressure or temperature changes.

Application

Treated Water
River Water
Sea Water
Potable Water
Demineralized Water
Glycol/water mix
Hydraulic System
