BUYER'S GUIDE

What is an Explosion Proof Ultrasonic Flow Meter?

Hazardous area clamp on meters are built for locations where flammable gases or vapors may be present and where electrical equipment must be contained or intrinsically safe. It uses transit time ultrasonic signals to measure flow from the outside of the pipe, but the transmitter and enclosure are certified for hazardous locations. These sensors mount on the outside of the pipe, which keeps the line sealed and avoids any intrusive work that could introduce risk in a classified zone. Technicians use them in refineries, chemical plants, fuel handling systems, and other industrial sites where safety rules prevent the use of standard meters. Explosion proof and intrinsically safe designs allow the meter to operate inside Zone 1 or Zone 2 areas while still providing steady, reliable flow data for process control and system monitoring.

When would you chose Exposion Proof Clamp On technology?

An explosion proof clamp on system is installed when you need flow measurement in a hazardous location and you cannot open the pipe or introduce any device that might spark. It is used on chemical lines, tank farm transfers, refinery loops, loading racks, and anywhere flammable materials are handled. Since the sensors are external, the line stays sealed and the process keeps running during installation.

This approach makes sense when a site needs stable flow data inside a classified area but wants to avoid intrusive work. The transmitter can provide analog, pulse, or digital signals to control rooms while staying within the boundaries of the area classification. It also gives you access to flow information on older or high pressure piping where cutting or welding would be costly or risky. The system stays in place long term and supplies operators with real time flow and trend information without compromising safety.

Advantages of Clamp on Flow Technology

  • No contact with the process
  • No need to open the pipe
  • Maintains system integrity in classified zones
  • Meets hazardous area certification requirements
  • Zero pressure loss
  • Minimizes hot work permits
  • Suitable for high pressure or corrosive lines
  • Easier installation compared to inline solutions
  • Provides continuous flow data to control systems
  • Reduces downtime and safety risk

Top Hazardous Areas Clamp On Flow Meters

UX5000 Explosion Proof Clamp on Ultrasonic Flow Meter

The UX5000 is a fixed clamp on flow meter designed for hazardous and heavy duty industrial environments. It installs on the outside of the pipe, so the line stays sealed and the system stays online during installation. The meter is certified for Zone 1 and Zone 2 hazardous areas and carries Class I Division I approvals for flammable atmospheres. The measurement system is intrinsically safe, and the electronics are split between a remote measurement unit and a separate display, which gives more flexibility in layouts where hazardous-area rules determine where each component can be placed.

Technicians choose the UX5000 when the application involves flammable liquids, vapors, or challenging industrial conditions where intrusive meters are not allowed. It is used across chemical plants, refineries, oil handling systems, and industrial water lines. The sensors clamp to metal guiderails and remain fully outside the process, providing accurate flow readings while maintaining the required safety barriers in hazardous zones. The split architecture also helps when sensors need to be placed in the classified area while the interface or controls must remain in a safer location.

The UX5000 offers single or dual channel setups, remote configuration, and multiple output options including active 4 to 20 milliamp, relay outputs, and Modbus RTU. The system is built with IP66 housings and industrial grade materials to handle harsh environments. Because it is a noninvasive meter with hazardous-area approvals, it provides a practical long term solution for flow monitoring where safety classification prevents the use of standard clamp on or inline devices.
