WARNING INJECTION HAZARD Spray from leaks, or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin can also cause serious injury. Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medical attention. Do not stop or deflect fluid leaks with your hand, body, glove, or rag.
Installation Installing the Flow Meter WARNING FIRE, EXPLOSION, AND ELECTRIC SHOCK HAZARD To reduce the risk of fire, explosion, or electric shock: All electrical equipment must only be installed by a qualified electrician. Understand and follow your local code and safety regulations for hazardous location wiring of intrinsically safe circuits.
Installation 2. Always ground the fluid supply unit, using one of the following options: Grounding WARNING FIRE, EXPLOSION, AND ELECTRIC SHOCK HAZARD Proper electrical grounding of your system is essential. For your safety, read the warning section, FIRE, EXPLOSION, OR ELECTRIC SHOCK HAZARD, on page 3. 1. Ground the flow meter by connecting a grounded cable to the sensor.
Operation Pressure Relief Procedure WARNING INJECTION HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you: are instructed to relieve the pressure, stop spraying, check or service any of the system equipment. 1.
Troubleshooting WARNING NOTE: The sensor is not a serviceable part. Replace it if it is malfunctioning. INJECTION HAZARD To reduce the risk of an injection injury or other serious injury, follow the Pressure Relief Procedure on page 6 before checking or servicing the meter assembly. Problem Cause Solution No flow volume displayed at monitoring unit Flow volume is too low to measure Increase flow volume. Fluid is not flowing See Problem: Fluid is not flowing, below. Damaged cable Replace cable.

Maintenance WARNING FIRE AND EXPLOSION HAZARD If the meter is not installed in an intrinsically safe installation, make sure the power is off or the electronic sensor is disconnected before wiping the outside of the meter clean with a cloth dampened in a compatible solvent or flushing the meter. CAUTION Do not immerse the meter in solvent with the electronic sensor installed. Solvent could damage the electrical components. Air purge is not recommended for any gear-type flow meter.
Maintenance Cleaning or Servicing the Meter Chamber WARNING INJECTION HAZARD To reduce the risk of an injection injury or other serious injury, follow the Pressure Relief Procedure on page 6 whenever you are instructed to relieve pressure. WARNING FIRE, EXPLOSION, AND ELECTRIC SHOCK HAZARD Installing and servicing this equipment requires access to parts that may cause electric shock or other serious injury if the work is not performed properly.
