KEY INSTRUMENTS FLOWMETERS

FR Series Flow Meters

FR Series acrylic flowmeters feature over 60 standard air or water scales with 10:1 rangeability. Manufactured of durable one piece crystal clear acrylic, these meters measure air flow from 50 CM to 4000 LPM and liquid flow from 4 CCM to 20 GPM. Standard features include easy to read English or Metric scales. Brass or stainless steel 1/8" FNPT fittings are supplied with the FR2000/4000 Series meters while 1/4" FNPT is standard on the FR4500 units. The FR5000 Series features 1" FNPT PVC connections. An optional needle control valve is available for the FR2000/4000/4500 models. Private labels, special designs, and calibration services are available to meet your needs.

MODEL FR2000

The FR2000 Series flowmeter was designed to combine quality, precision, versatility and economy. The machined acrylic body and wetted components are ideally suited for measuring or controlling non-corrosive gases and fluids. These units are typically used in sampling equipment,

gas analyzers, medical instrumentation, water purification and reverse osmosis systems. They are panel mountable and easily converted for laboratory bench top use by using the optional tripod.

Design Features:

• Easy to read English or Metric Scale
• Durable one piece machined clear acrylic
• Easy to install
• Tube taper tolerances provide stable, accurate flow measurement
• Panel mountable, bench to usable
• For flow control, brass or stainless steel needle valves can be specified
• Brass with Buna N or Stainless Steel with Viton o-rings and 1/8" FNPT fittings

Specifications:

• Flow Range: Turn down ratio is 10:1 with one float
• Standard Accuracy: +/- 5% Full Scale
• Maximum Operating Pressure: 100 PSIG/6.9 BARS
• Maximum Operating Temperature: 150蚌/65.5蚓
• Repeatability: +/- .5% Full Scale
