The 2151P Flow System is similar to the 2151 intrinsically safe Area Velocity Flow Meter, but is designed to operate from AC power for long-term or permanent applications rather than from battery power for shorter-term, portable applications. Like all 2100 Series modules, the 2151P is set up via connection to a computer running Flowlink Software.
The intrinsically safe design of the 2151P module and flow sensor allows them to be installed in Class I, Division 1, Groups C and D hazardous locations. The concept of intrinsic safety is to limit the energy available to a given circuit or device to a level where electrical discharge (sparking) cannot ignite the hazardous (flammable or explosive) atmosphere. With no spark ignition possible, the equipment can operate safely in areas with hazardous atmospheres.
