Sensor
①
Meter body assembly
It consists of a measuring pipe and a bluff body. As the metered fluid runs, Karman vortices form
and shed downstream of the bluff body.
②
Sensor assembly
The assembly contains sensors to detect Karman vortices. It consists of a sensor housing,
thermistor sensors, and sensor signal detecting circuit. By closing the block valves in the sensor
housing, the operator can inspect or service the assembly without interrupting the flow in the line.

Converter (PA21)
The converter transforms the signal from the sensor into flow rate output (pulse signal of the same unit as
the meter factor). Install the converter on a 2" steel pipe post, using U-bolts in a location easy to access with
desirable environment.

NOTE: About explosionproof construction
In this flowmeter, the converter is built flameproof and increasing safety explosionproof construction
(terminal box on the sensor assembly).
The sensor is built flameproof and intrinsically safe explosionproof construction.
