Section 2 General information 2.1 Safety information Please read this entire manual before unpacking, setting up, or operating this equipment. Pay attention to all danger and caution statements. Failure to do so could result in serious injury to the operator or damage to the equipment. To ensure that the protection provided by this equipment is not impaired, do not use or install this equipment in any manner other than that specified in this manual.
Remarque importante : Les informations suivantes sont fournies dans le but d'informer les utilisateurs des capteurs Flo-Dar des dangers et des risques associés à l'accès aux espaces confinés. On April 15, 1993, OSHA’s final ruling on CFR 1910.146, Permit Required Confined Spaces, became law.
2.2 Product overview The Flo-Dar Intrinsically Safe Sensor measures the flow velocity and liquid depth in open channels using radar and ultrasonic technology. The unit is designed to withstand submersion during surcharge conditions. The optional surcharge velocity sensor provides velocity measurements during surcharge conditions.
à des préjudices constituant un danger de mort et/ou des dégâts sur les installations. The Flo-Dar Intrinsically Safe Sensor is listed as intrinsically safe for Class 1, Zone 1, Group IIB Hazardous Locations. This means that the circuits within these sensors cannot produce a spark or thermal effect that could ignite a mixture of flammable or combustible gases when installed properly.
Mount the Flo-Dar sensor above the open channel on the wall of the manhole. For hazardous locations, a barrier must be installed outside of the hazardous area. To prevent damage to the enclosure, do not mount the Flo-Dar sensor in a location that receives direct sunlight.
SVS component and the logger or controller. 3.3.2.1 Install the barrier A barrier must be installed when the Flo-Dar sensor is installed in a hazardous location as defined in section 3.1 on page 9.
Procedure 1. Remove the four screws from the cover of the barrier. Remove the cover. 2. Insert the cable from the Flo-Dar sensor through the strain relief fitting on the side of the barrier with the hazardous area connection label (Figure 3 on page 14).
