Description
GOATACURA 4” Woltmann helix water meter is specifically engineered for industrial cold water applications where accuracy, durability, and low maintenance are critical. The helical-blade rotor design provides excellent accuracy across a wide flow range with minimal pressure loss. The magnetic drive eliminates mechanical seal leakage, while the dry dial register ensures fog-free, clear reading even after years of service.
The epoxy-coated cast iron body is built to withstand harsh factory environments – impact, humidity, and mild chemicals. All wetted parts are corrosion-resistant. The meter includes a factory-calibrated pulse output (reed switch, 1 pulse/100 gal) with a 1.5m two-conductor cable, ready to connect to your existing monitoring infrastructure.
