Technical Specifications

DVS205 Dual-Variable Sensor

The DVS205 Dual-Variable Sensor (DVS205)

provides static pressure and differential pressure

inputs to a FloBoss™ 103, FloBoss 107E, or FloBoss

500-Series Flow Manager. The DVS205

communicates via a serial format with the FloBoss.

Variables

Functionally, the DVS205 is a digital transmitter that

measures two flow-related variables simultaneously:

differential pressure and static pressure. These

variables are continuously available to the FloBoss

unit that polls the DVS205.

Transducer and Electronics

The DVS205 contains a transducer and an

electronics circuit. The transducer uses capacitance-

cell technology to sense differential pressure and

piezoresistive technology to sense the static

(absolute or gauge) pressure.

The transducer electronics convert the pressure

variables directly into a digital format, allowing

accurate correction and compensation. A

microprocessor linearizes and corrects the raw

pressure signals (from the sensor) using

characterization data stored in non-volatile memory.

The electronics also allow the DVS205 to

communicate with a FloBoss using a Serial

Peripheral Interface (SPI).

Accuracy

Two versions of the DVS205 are available:

 205P with reference accuracy of 0.075% of the

full span.

 205E with reference accuracy of 0.10% of the

full span.

Mounting

The DVS205 is factory installed on a FloBoss™ 103,

FloBoss 107E, or FloBoss 500-Series Flow Manager

to comply with agency requirements. Attached to the

bottom of the sensor body is a Coplanar™ flange.

This flange allows the DVS205 to mount on an

integral orifice assembly or manifold valve.
