Glass Tube Varea-Meter

Glass Tube Varea-Meter® Flow Meter

Varea-Meters units are designed for precise measurement of liquid and gas flow rates. Metering accuracy is 2% of full scale over a 10:1 range. The advanced design of the float and the tapered tube extends the meter capacity to match that of comparable meters costing much more.

Varea-Meter® flow meters are available in a wide variety of tube sizes and configurations. The glass tube version includes a one piece stainless steel frame and beaded guide tube with a detached scale for calibration in most engineering units.

Tube sizes are available from 3/8" to 1 1/2". Frame sizes can be 5" or 10". The end fitting material is available in 316 stainless steel or PVC. Standard float construction is 316 stainless steel (Hastelloy "C" is optional).

Beaded guide tubes are available with 5- or 10-inch scales. End fittings for vertical and horizontal connections come in NPT sizes. Choice of wetted parts materials such as 316 stainless, Kynar®, Buna-N, and Viton® give a good balance between cost and maximum corrosion resistance.

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.

Varea-Meter Flow Controller 5700 500x500 100dpi

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.

Varea-Meter Flow Meters 5750 and 5800 800x500 100dpi

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
