Metal Tube Varea-Meter®

Metal Tube Varea-Meter® Flow Meters
Metal Tube Varea-Meter® Variable Flow Meters are designed for the measurement of high-volume flows of aggressive liquids and gases. The advanced design of the float and the tapered tube extends the meter capacity to match that of comparable meters costing much more. The 316 stainless steel construction makes these meters suitable for a broad spectrum of applications.
Metal Tube Varea-Meter® Variable Flow Meters are easy to install, calibrate and configure. They provide reliable long term performance in gas or liquid service. Available in a variety of tube sizes (½-, ¾-, 1-, and 1½ inches) and flange facings and ratings, these flow meters measure over a 10:1 range for aggressive fluids at high temperatures and pressures. Metering accuracy is 2% of full scale.
Anti-Magnetic Particle Float has a reduced flux density and is located above the metering disk. This discourages accumulation of magnetic particles, especially on the disk edge where they can cause errors in indication. Meter design directs the flow into a pattern, which scrubs the float and guides clean. The Metal Tube Varea-Meter® unit is ideal for suspensions and slurries.
When the float is at rest, nothing projects beyond the flanges. Spool pieces are not required for installation and a frequent cause of damage when removing meters from a line is gone. In and out piping is vertical.
For reliable indication, a powerful magnetic linkage exists between the float magnet and the indicator magnets. Transmission and indication are reliable even under sudden flow surges.
The indicator unit, with optional 4-20mA transmitter or flow switch, are independent. A mounting clamp attaches each to the meter tube. The same clamp attaches the transmitter or flow switch 180 degrees from the indicator unit. Clearance between any of these units and the tube leaves room for steam or electric tracing.

Flow Controllers
The flow measurement product line offers three types of flow controllers:
- Series 5700 General Purpose Flow Controller
- Series 5750 High Pressure Flow Controller
- Series 5800 Purge Type Flow Controller.
Each is designed to maintain a constant set flow rate regardless of variations in the line pressure. All of these basic arrangements are suitable for gas and liquid service.
The Series 5700 General Purpose type has a broad range of applications. It can be used with almost any equipment or within any flow system in which the process fluid is compatible with 316 stainless steel construction.
It is ideally suited for the Armored Purge Meters, Armored Flow Meters, Glass-tube Varea-Meter® units, or as a stand-alone controller with other meter types.

The Series 5800 and 5750 purge type flow controllers are engineered specifically for use with the Glass-tube Purge Meters, Low-flow Meters, and Arma-View®II Armored Purge Meters. The Series 5800 purge-type flow controller is engineered specifically for use with glass-tube purge meters. The Series 5750 high pressure flow controller is designed for use with purge meters in high pressure and temperature applications (1000 PSI and 400 degF MAX). Both the 5800 and 5750 series controllers are offered in an inlet or outlet flow configuration for added versatility.
Features
- Simple, Direct Design. The clean, straight-through design makes it simple to integrate these controllers within a system. Installation piping is direct and uncomplicated.
- Reliable and Accurate Operation. These controllers maintain a constant set flow rate by sustaining a constant pressure drop across their orifices. The size of the orifice is varied while the pressure drop is held constant. This balance provides a set flow despite changes in the supply pressures.
-
Sturdy Construction. The housing and valve stem for all controllers is constructed of 316 SS, while the diaphragm is made from highly chemical resistant Teflon material.
Key Benefits
- Choice of integral and stand alone design allows for flexible installation options
- Easily adapt to existing meters
- Reliable and accurate operation despite changes in the supply pressures
- Chemically resistant to many process conditions
- Wide spectrum of flow rates and pressures allowable
- Easy to integrate controllers within the system with direct and uncomplicated
