The Series UV Ultra-View™ Polysulfone Flowmeter is an ultra-pure, laboratory grade flowmeter with a dual scale that measures flow in GPM and LPM of water, air and other compatible media. The Series UV is designed to withstand high temperatures up to 212°F (100°C) and pressures up to 150 psi (10.34 bar).
 
Product Applications
Monitor chill water flow
Reverse osmosis systems
Deionized water systems
Potable water systems
Remediation applications
 
Features :
 
Corrosion-resistant polysulfone body ideal for applications where other flowmeters fail saving replacement cost and time
Easy to clean body yields low maintenance costs
Polycarbonate shield protects internal scale increasing product operating life
Low installation costs with optional panel mount polysulfone fittings
 
Specification : 
 
Service: Compatible liquids or gases.
Wetted Materials: Polysulfone body and fittings, fluoroelastomer O-rings and virgin PTFE float.
Temperature Limits: 35 to 212°F (2 to 100°C); 35 to 130°F (2 to 54°C) for PVC fitting option.
Pressure Limits: 150 psi (10.34 bar).
Accuracy: ±2% FS @ 70°F ±2°F (21.1°C) and 14.7 psia (in line connection rating only).
Repeatability: ±1% FS @ 70 ±2°F (21.1°C) and 14.7 psia (in line connection rating only).
Process Connections: 1" female NPT. Optional 90° polysulfone elbow - 1" male NPT.
Scale Length: 6" (152.40 mm) - 7" (177.80 mm), depending on model.
Fitting Torque: Maximum 22 ft lb.
Weight: 1 lb (457 g) (for 20 GPM range).
 
CAUTION: Ball valves can have a "water cannon" effect on opening, creating pressure that exceeds the warranty ratings will damage the flowmeter.
Series UV Flowmeters are for indoor use only or areas without direct sunlight. Polysulfone is adversely affected by ultraviolet light.
