Armored Purge Meters

Armored Purge Meters - Metal Frame

The Armored Purge Meter operates over a 10:1 range. Scales are 1¼ inches long. The ½-inch meter has a GPH or SCFH scale; the ¾-inch meter, a GPM or SCFM scale. Each also has a percent scale.

The snubber on the magnetic float causes readings to steady out quickly. This gives true readings down to atmospheric pressures. The O-ring at the top of the float seals against the seat to prevent back flow through the meter. A port in the bottom of the meter body makes it easy to clean.

The stainless steel and welds in our Armored Purge Meters resists sulfides by conforming to NACE Standard MR-01-75 covering hydrogen sulfide-resistant surfaces. The 316 stainless steel body with Buna N or TFE O-rings gives corrosion resistance and reliable operation to 1500 psi (10 bar) and 800°F (427°C) (600°F (316°C) with flow switch).

At no time is the glass scale tube exposed to the process fluid. A stainless steel sheath encloses the O-ring sealed glass tube. General purpose or hazardous area flow switches are available.

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.

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
