ULTRA UF-II is a positive displacement type flowmeter equipped with a multi functioned electronic register (ULTRA Register) and is globally applied in tank truck loading systems and transactions of petroleum products in refineries.
The exclusive flowmeter is free from pulsation and releases minimal noise and vibration during operation with special spiral rotor design.
High accuracy flow measurement is guaranteed with a wide rangeability.

FEATURES

1. Constant rotor rotation speed, constant torque, constant flowrate with no pulsation results in low pressure loss and enables extremely quiet operation with minimum vibration.
2. Less rotor friction of the spiral rotors provides high durability.
3. Large discharge rate per rotation and relatively high rotation speed allows measurement of large volumes even with small nominal size.
4. Simple structure without the need of pilot gears.
5. The ULTRA register equipped with a CPU indicates total flow, resettable total flow, instantaneous flowrate and low battery alarm on the LCD by changing the mode selector.
6. Output signal is available in two channels simultaneously in the form of total flow (4/20 mA DC scaled or unscaled current pulse) and instantaneous flowrate signal (4 to 20mADC analog).
7. A complete series of explosionproof model also available.
8. With batch controller equipped ULTRA register, you can establish a simple batch control system.

Principle of Operation

Having a pair of rotors as revolving elements (see photo at right), the UF-ll is a positive displacement flowmeter which directly measures the volume of flowing fluid passing through. A pair of these spiral rotors are directly in gear with each other specially designed and precisely processed to achieve a zero slip factor. Operation principle is shown in the figure below. As the process fluid flows into the measuring chamber, the rotors are, under a differential pressure that exists between the inlet and outlet, made to rotate in the direction opposite to each other as shown by arrows.
In figure ''A'', viewed on a plane illustration, a rotational force acts only on the first rotor; no rotational force acting on the second. But these rotors in actual are twisted as shown in the photo. Each rotor receives the same rotational force, resulting in uniform rotor rotation and uniform rotational torque with no pulsation in the flow being discharged.
Each space formed by the rotors and the inner wall of the measuring chamber serves as a pocket (colored in blue) and, in one complete rotor revolution, the process fluid of eight times the volume of this pocket is delivered to the discharge outlet. Therefore, taking this rotor rotation by rotational frequency, we can measure the exact total volume of the process material delivered, while the instantaneous flowrate can be measured by the rotational velocity.

Connection with receiver

ULTRA UF-Ⅱ is available in the following types: a battery driven type (without output) that requires no external power supply and an external power supply type (with pulse output and analog output).
