Model D118 -Flowmeter With Explosion-proof Distribution Box for Petrochemical
D118 Wall Mount Type Ultrasonic Flow Meter. HRMD Series Explosion-proof Distribution Boxes. For Petrochemical, Liquid Blending Systems, Single pot granulator, Oil and derivatives, Explosion-proof Distribution Box and D118 ultrasonic flowmeter are two distinct components used in different aspects of industrial settings. Let`s understand each of them separately: Explosion-proof Distribution Box: An Explosion-proof Distribution Box, also known as an Explosion-proof Junction Box or Enclosure, is designed to contain electrical equipment and wiring in potentially hazardous environments. These environments may have flammable gases, vapors, or dust particles that could ignite and cause an explosion. The distribution box is constructed with materials and engineering techniques to prevent the ignition of surrounding flammable substances. It ensures that any sparks, heat, or electrical arcs generated within the box are contained, thus minimizing the risk of an explosion.

- Safety Compliance
- Operator Safety
D118 Ultrasonic Flowmeter: An ultrasonic flowmeter is a device used to measure the flow rate of a fluid by utilizing ultrasonic waves. It operates on the principle of measuring the time it takes for ultrasonic signals to travel through a medium. The flowmeter consists of sensors that emit and receive ultrasonic signals across the flow path. By analyzing the time difference between upstream and downstream signals, the flowmeter can calculate the velocity and volume flow rate of the fluid.
Regarding the relationship between an Explosion-proof Distribution Box and D118 ultrasonic flowmeter, it primarily lies in their application within hazardous environments. In certain industrial settings, where flammable substances are present, it is crucial to ensure that all electrical equipment, including the ultrasonic flowmeter, is appropriately protected. Therefore, an Explosion-proof Distribution Box can be used to enclose and safeguard the electrical connections and components of an ultrasonic flowmeter, ensuring it operates safely in such hazardous locations.
By placing the ultrasonic flowmeter within an Explosion-proof Distribution Box, the risk of ignition or explosion due to electrical faults or sparks is significantly reduced. This protective measure ensures compliance with safety regulations and mitigates potential hazards in environments where explosive atmospheres are a concern.
