The Model P Single Flow Tube Meter (Rotameter), offered by AskA Solution in Saudi Arabia, is a precision instrument engineered for low flow rates with the simplicity, versatility, and economy of a classic variable area meter. Model P single flow tube meter is deal for various applications, it is particularly effective in metering carrier gases in chromatography, managing gas flows in manufacturing processes, and measuring both liquids and gases in labs and pilot plants. The 150 mm meter with CV™ Valve comes fully assembled with standard mounting fittings in various materials, a robust magnifying front shield, a back plate, and an optional built-in control valve. Each unit has flow tubes selected from Flow Capacities tables, ensuring reliable performance across diverse industrial settings.

Flow tubes for these variable area flow meters (rotameters) are available with two types of scales, suitable for different types of applications

Direct Reading Scales:

Direct reading scales indicate the flow rates of liquids and gases in engineering units such as [mL/min], standard cubic feet per hour [scfh], etc. Such scales are designed exclusively for a specific gas or liquid at a given set of pressure and temperature parameters and are valid for the associated units of flow only. The convenience of direct reading scale designs should be weighed against the applicability limitations. Generally, direct reading scales are most suited to OEM applications.

Universal Millimeter (Correlated) Scales:

Millimetre scales indicate the vertical position of the spherical float within the metering tube as the flow increases or decreases.

It is necessary to use flow tables or graphs supplied to correlate float-referenced readings with actual volumetric flow rates.

Alternatively, the flow tables and graphs can be found using our online Flow-Tube Calibration Data Library by looking up your flow tube part number.

The advantage of universal-type scales is the ability to utilize a given flow meter for a great number of different fluids at diverse pressure and temperature conditions, which is generally preferred in applications in laboratories, etc.

Built-in Valves:

Model P single flow tube meter are available with built-in needle valves (CV™), high-precision metering valves (MFV™) with “non-rising stems,” or no valves. The higher cost of MFV™ valves is justified whenever high sensitivity control and resolution are desirable, particularly in conjunction with metering tubes of very low flow rates.

Generally, for gas metering, it is recommended that valves be positioned at inlets (bottom). For liquids, valves may be positioned either at inlets or outlets (top). For vacuum services, valves must be mounted at outlets. If unspecified when ordering, meters will be shipped with valves mounted at the inlets.

What are the critical applications of the Model P Single Flow Tube Meter?

It is ideal for low-flow measurement applications, such as carrier gas metering in chromatography, controlling gas flows in manufacturing applications, and measuring liquids and gases in laboratory and pilot plants.

What is the difference between direct reading scales and universal millimetre scales?

Direct reading scales show flow rates in specific engineering units, such as mL/min or scfh, for a particular gas or liquid at set conditions. Universal millimetre scales require correlation with flow tables and are versatile. They allow the meter to measure various fluids under different pressures and temperatures, which is particularly useful in laboratory applications.

What are the accuracies for Model P Flow Meter?

The standard resolution is ±2% full scale for mm scales (except in specific tubes) and ±5% for direct reading scales. Calibration improves resolution to ±1% of full scale.

Are there different valve options available for this flow meter?

The Model P provides choices such as CV™ needle valves, MFV™ high-precision metering valves, or no valves. MFV™ valves are best suited for applications that are highly sensitive and require exact control, particularly in low flow rates.

What are the maximum operating pressure and temperature for this meter?

The Model P Single Flow Tube Meter is supplied with a maximum pressure of 200 psig (13.8 bars) and a maximum temperature of 250°F (121°C).

Confirm Compatibility of Materials: Ensure the materials used in the meter—such as borosilicate glass flow tubes, stainless steel or carboloy floats, and various O-rings—are compatible with the fluids to be measured.

Use Appropriate Valve Positioning: For gas metering, position inlet valves at the bottom, and for liquids, either one may be positioned at the inlet or outlet (top). Valves must be located at the outlet to ensure proper flow control for vacuum services.

Avoid Operation Beyond Maximum Specifications: Do not exceed the rated maximum pressure of 200 psig or the temperature limit of 250°F, as doing so can damage this meter and adversely affect its measurement.

Handle glass flow tubes with care: Borosilicate glass flows and breaks easily. So, care needs to be exercised while designing and installing to avoid any negative impacts or pressure tolerance in this regard.

Verify Scale Type for Correct Readings: Determine if the meter takes a direct reading or a universal scale. Using flow tables or calibration data for universal scales, determine correct readings and their applications.
