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.
