For low-capacity, low pressure applications we offer glass tube purges meters with stainless steel or PVDF frames. Purge meters are specifically designed for purging instruments cases and control lines, and are readily adapted to liquid-level indication, sampling, liquid specific gravity determination and similar applications. The PVDF frame unit is available for aggressive fluids and highly corrosive atmospheres. For low flow, higher pressure application armored purge meters are available.

For high volume flows glass-tube and metal tube meters are available in a variety of sizes and configurations for metering both air and liquid. For very aggressive fluids a TFE-lined meter is available. For lower pressure and temperature applications a PVC-Tube meter is available.
