Advantages of Aoniuba flow meters
Thread Content
The Anubaa flow meter belongs to the category of average velocity tube flow meters. Its basic structure consists of a hollow metal tube in the middle, with paired pressure measurement holes drilled along the direction of fluid flow. When used in practice, the Anubaa flow meter is installed vertically relative to the axis of the process pipeline; as the fluid passes through it, it creates a pressure difference similar to that produced by a standard orifice plate. Features that distinguish Anubaa flow meters from other pipe-type flow meters: 1. Simple installation – Anubaa flow meters are very easy to install; all that is required is to make a small hole in the process pipeline, weld on a connector, insert the flow meter, and then tighten the clamp. 2. Ability to be removed and installed without shutting down production – This is a feature that other pipe-type flow meters do not possess. Anubaa flow meters can be removed and installed without interrupting production, which reduces the workload for instrument maintenance personnel. 3. Low requirements for the length of straight sections: When installed on-site, the straight sections before and after the Anubis flow meter require only 1/3 of those needed for throttling devices such as standard orifice plates, **which reduces the investment in the process pipelines on site.4. Significant energy-saving effects: Tests have shown that the pressure loss associated with the Anubis flow meter is very low; under the same conditions, it is less than 5% of that incurred by throttling devices like standard orifice plates. Therefore, using the Anubis flow meter **reduces power consumption, resulting in notable energy savings.
In addition to these advantages, it also features a wide range of applicable applications, good long-term stability, reduced maintenance needs, and a low cost.
What types of media is Aniuoba suitable for measuring? Could you give more examples? What types of media is it not suitable for measuring?
Gases and liquids are both fine; avoid measuring substances with high viscosity, such as coke oven gas. It is also necessary to avoid clogging, so there are requirements regarding particle size as well

Installing Anubaa is relatively simple, but it must be installed in accordance with the requirements. There are models that support online plug-and-play without shutdown, but those are special versions; not all models allow for such operation. Installation requires making holes while the system is under pressure, which is a challenging task that demands specialized equipment or personnel. Instrument manufacturers do not provide equipment for making holes under pressure. Of course, if you insist on purchasing such equipment, it will be more expensive than the instruments themselves.
What are the measurement stability and reliability like?
In fact, all those that can be disassembled under pressure are equipped with isolation valves for cutting off the flow. Therefore, the instrument must be designed, or can be designed, to be plug-in type, such that once it is pulled out to a certain extent, the shut-off valve closes. Actually, I would prefer that instruments require as little maintenance as possible; for example, most of the vortex flow meters we use have never needed to be disassembled or repaired over a period of more than a decade. Another option is to have the detection of the \"vulnerable\" components done externally, such as with Rosemount vortex flowmeters. But why become vulnerable? I hope that whether it is operated online or offline, the failure rate should be low and the maintenance requirement should be minimal. This is the direction I strive for during selection, procurement, and installation.
There’s no problem as long as it’s used in the right applications and installed properly
Anyway, the one my company used didn’t work well at all; we wasted tens of thousands of dollars on it. We switched to a cheaper Yokogawa vortex flow meter, and it works great.

During installation, this shut-off valve is first welded to the pipeline; then, specialized equipment for making openings under pressure is used to pass through this valve while ensuring a seal with it. An opening is created in the pipeline, after which the equipment used for making the opening is removed, the shut-off valve is closed, any residual pressure is released, and the equipment is taken out. Of course, the structure of this cut-off valve and hole-making device is special; after the hole is made, installation is carried out, and the same procedures are followed during maintenance – by moving the part that inserts into the pipe upward to cut off the flow, release pressure, and then remove it. It is said that a device for making holes, when supplied by the manufacturer as a complete set, can be more expensive than the instruments themselves; it might cost over a hundred thousand yuan. In China, those who specialize in making holes under pressure charge roughly ten thousand yuan per hole
