SVF EV Series Plastic Tube Variable-Area Flow Meter for Versatile Positioning

SVF EV series plastic tube variable-area flow meter is a variable area flow meter, its main material is polycarbonate (PC) or polysulfone (PSU), so it has excellent high temperature resistance and corrosion resistance. The unique spring design allows the flowmeter to be placed at any angle without affecting accuracy, and the red flow card label is easy to use and identify, making it the most readable flow meter among similar products.
