Measuring Range
The velocity range is 0.3m/s to 15m/s. The minimum measurable speed can be one percent (1%) of the full range.

Accuracy

DN (mm)	Velocity m/s	Accuracy
25 ~ 1200	0.1~0.3	±0.25%FS
	0.3~1	±0.5%R
	1~15	±0.3%R
%FS:Relative range;%R:Relative measured

Analog Output
Current output: fully-isolated 0 - 10mA / 4 - 20mA
Load resistance: 0 to 1.5kΩ at 0 - 10mA; 0 to 750Ω at 4 - 20mA
Base error: add ±10μA on top of the measurement error

Frequency Output
Frequency output is proportional to the flow percentage of the full range. It provides fully isolated transistor open collector frequency output ranged from 1 to 5000 Hz. The external DC power supply should not exceed 35V and maximum collector current is 250mA.

Pulse Output
The converter can output up to 5000cp/s pulse series, which is dedicated to external totalization. Pulse factor is defined as pulse count per unit volume or mass. It can be set to 0001-9999p/L, 0001-9999p/m3, 0001~9999p/kg or 0001~9999p/t. Pulse width is selectable from 16ms, 33 ms, 66mm, 99ms or auto square wave. Photo-coupler isolated transistor open collector circuit is used for pulse output. The external DC power supply should not exceed 35V and maximum collector current is 250mA.

Showing Flow Direction & Range
The converter is capable of measuring both forward and reverse flow and recognizing its direction. The converter outputs 0V low level for forward flow, while +12V high level for reverse flow.

Alarm Out
Two channels of photo-coupler isolated open collector circuit are used for alarm signal output. There are two alarm outputs: high limit alarm and low limit alarm. The external DC power supply should not exceed 35V and maximum collector current is 250mA.

Communication
The RS485, RS232C, HART, Profibus, MODBUS communication interface are embedded in the converter. Surge absorber is optional to protect the interface and converter.

Damping Constant
Damping time is optional from 0.2 to 100s

Input Contact
External contact ON (close) or OFF (open) signal can be used to remotely control the start/stop or reset of internal counter.

Display Function
Flow rate can be displayed either in engineering units or in percent of span. Totalized volume in any engineering unit can be displayed by setting a totalizing factor.

Self Diagnostics Function
Converter failure, flow tube failure, erroneous setting, etc. can be diagnosed and displayed.

Data Security During Power Failure
Data storage by EEPROM - no back-up battery required

Electrical Connection
ISO M20´1.5 female

Terminal Connection
M4 size screw terminal

Case Material
