Matheson’s PM-1000 Series acrylic flowmeters are a practical, low-cost approach to low flow rate indication of gases. A broad range of industrial applications involving non-corrosive fluids, normal atmospheres and less stringent accuracy demands are within the scope of this simplified, plain tapered tube design. State-of-the-art manufacturing techniques ensure each meter meets the performance demands of these applications. The PM-1000 Series are direct reading for air, and are available in either English or Metric units. Choose between a black glass or stainless steel float. Complete annealing during production ensures each meter body is stress free. No plastic threading is used, eliminating crazing and fracture of the acrylic. An extruded aluminum support frame for the meter body absorbs all connection strain. Support frame flanges and lock nuts provide for a variety of panel mounting arrangements. The simplified design of this meter allows quick, easy maintenance. High impact strength of the acrylic meter block completes this dependable design.
Valve Options
• Utility valve for those who desire control as well as indication
• No valve for those who just want indication
