Azbil's AX24R Multivariable Reduced Bore Vortex Flowmeter
Azbil’s AX24R Multivariable Vortex Flowmeter offers accurate and reliable flow metering in a multivariable design. The multivariable design incorporates a high-accuracy velocity sensor, a precision platinum RTD temperature sensor, and a solid-state pressure transducer. The meter’s process connections match the line size but use integrated reducing flanges, and the meter body reduces in diameter, increasing the fluid velocity through the meter. Increasing the velocity in this fashion extends the meter’s measuring range to capture lower flow rates that a full line size meter might miss.
THE AZBIL AX24R EXTENDS MEASURING RANGE AT LOWER FLOW RATES AND SAVES COST. LEARN HOW HERE.

Understanding the Importance of Pressure Drop When Using Flowmeters
The pressure inside a pipe can vary from the pressure outside of the process. Friction or a physical obstruction in the pipe may cause a pressure drop in the system, resulting in a loss of line pressure.
Figure 1 shows a high and robust pressure reading at point "A," followed by the pipe narrowing. The pressure reading then drops at point "B." This phenomenon is the definition of pressure drop.
Figure 1: Visual example of a pressure drop in a pipe where a narrowing of the pipe causes a drop in
pressure from point “A” to point “B”.
Maintaining pressure can be vital to the device's operation, its equipment components, or the process performance.
Pressure Drop Rates and Gas Flow Technologies
There are several flow measurement technologies available on the market today. Each technology uses a different method to measure a pipe flow rate, but some are known to cause undesirable pressure drops. It is unrecoverable once the pressure decreases. Let's look at some of the most popular flow measurement technologies and their pressure drop scores.
Thermal Mass Flow Meters Have a Negligible Pressure Drop
Other Advantages of Thermal Mass Flow Measuring
There are many advantages of using thermal gas mass flow meters over other flow measurement technologies:
- Air and gas mass flow measurements in standard volumetric units (e.g., SCFM or NM3/H) or mass units (e.g., LBS/M or KG/H)
- There is no need for extra pressure or temperature compensation.
- Repeatability and an extremely wide measurement range: up to 1000:1 (100:1 typical)
- 4-20mA linear output proportional to mass flow rate
- There are no moving parts.
- Insertion, Inline, and remote* models are all available.
- Flow rate and temperature are measured.
Fox Thermal is revolutionizing thermal mass flow measurement technology with a series of innovations:

Airflow Control Within Close Tolerances Saves Money
In drying and coating processes in the pharmaceutical, food and beverage, chemical, petrochemical, and mining sectors, millions of dollars are lost daily - in fluidized beds, rotary drums, flash dryers, kilns, and similar processes. Because of improper air and product feeds, these devices' failure can cause validation problems, causing downtime, re-validation, and loss of both goods and profits. It's vital to control airflow through these devices.
PROBLEM
How can vital processes and devices that need to work within tight tolerances over a broad operating range be supported with continuous air mass flow at a regulated air temperature?
1) Improving Production Efficiency
The off-specification product must be recycled or wasted. This process is too costly, especially in the validated industries. Precise control of airflow and air temperature is essential to maintain high product quality, reduce waste, and increase uptime. The performance of many processes would benefit from measuring the mass flow of process air. Also, limited flow meter turndown often constrains operational flexibility - primarily when requirements cover a wide range of operating conditions.
2) Dealing with Limited Straight Pipe Runs
Airflow meters incorporated into process equipment are often inaccurate due to the short upstream and downstream straight pipe run. The installation of a good straight run can quickly become problematic in tight quarters, so other solutions are needed.
3) Reducing Plugging and Coating
Most process equipment designs do not include relatively dirty exhaust flow measurements, even though they can provide significant operational benefits. They are often not included because exhaust flow meters can become coated and plugged when particulates are present — reducing flow meter accuracy.
Products from Air Monitor solve these issues by enhancing the reliability of your airflow meters by improving their accuracy over a wide range of flow rates, thus improving the process's efficiency, improving the product's consistency, and increasing production rates to reduce fuel spending.
