The SureSig® passage indicator counts everything that runs through the launcher, receiver, or pipeline with a stainless-steel bi-directional trigger—and then seamlessly relays that data with your PLC or SCADA system.
All units are corrosion-resistant, explosion-proof, and come weather-sealed with a variety of seal material options. Plus, the SureSig® is rated for hazardous location support through Class 1, Div. 2, and can be deployed in any condition.
Quick, Easy Installation
The SureSig® design features a threaded mounting nipple sized to the wall thickness of your specific pipeline, making for easy unit installation by practically anyone and easy connection to electronic systems.
