Converter performance

Power supply: single-phase AC power (85-265) V, (45-63)Hz, power is less than 20W; DC power supply (11-40) VDC.

Converter display and programming operation: 4 film keys can set all parameters and can also program the converter by using foreign receiver or PC machine (RS485, RS232), high definition backlight LCD display, empty pipe detection and self-diagnosis function.

Digital communication: RS485, RS232, MODBUS and REMOTE, with lightning protection.

Output signal

Current output: two-way circuit, full isolation (0-10) mA/(4-20)mA; load resistance: (0-10) mA, (0-1.5) KΩ; (4-20)mA , (0-750) Ω.

Frequency output: forward and reverse flow output, the upper limit of output frequency can be set in the range of (1-5000) HZ. Transistor collector is with photoelectric isolation output in both directions. The external power supply is not more than 35V, and the maximum collector current is 250mA when it is turned on.

Pulse output: forward and reverse flow output, output pulse up to 5000cp/s. Pulse equivalents are 0.001L-1.0m3/cP. Pulse width is automatically set to 20ms or square wave. Open collector output of transistor with photoelectric isolation. The external power supply is not more than 35V, and the maximum collector current is 250mA when it is turned on.

Flow direction indication output: this flowmeter can measure fluid flow in positive and negative direction. The direction of the fluid flow can also be judged.High level of output + 10V for displaying forward flow, and low level of 0V for reverse fluid flow output.

Alarm output: two transistor collector open circuit alarm output with photoelectric isolation. The external power supply is not more than 35V, and the maximum collector current is 250mA when it is turned on. Alarm state: fluid air pipe, excitation line break, flow over limit.

Parameter setting

Measurement for pipe caliber

Electromagnetic flowmeter converter supporting sensor diameter scope：3～3200mm.

At the same time, caliber fine-tuning can be set for non-general caliber or caliber error is large.Example, 50 -01 mm (49 mm) 50 + 01mm (51 mm).

The damping time setting

Long measurement damping time can improve the stability of instrument flow display and output signal, which is suitable for the total cumulative pulsation flow measurement.Short measurement damping time appears as fast measurement response speed and it is suitable for production process control.The measured damping time can be arbitrarily set at 1-99.

Flux unit

Select the flow display unit in the parameters, and the instrument flow display unit is: L/s, L/m, L/h, m³/s, m³/m, m³/h .Users can select an appropriate flow display unit according to the process requirements and usage habits.

Flow decimal bit setting

Set the instantaneous flow decimal display digits and it is divided into automatic setting and manual setting.

*Under the automatic setting state, the instantaneous flow decimal number is automatically selected according to the caliber size;

* Under the manual setting state, the instantaneous flow decimal digits are set according to the user setting, and the 0,1,2,3 decimal digits can be set;

The user can set it according to different application conditions and different measurement scales.

Flow integrating unit

The converter display is a 9-bit counter with a maximum allowable count value of 9999999999. Use integrating unit in L, m³ (liter, cubic meter).

The flow integrating equivalent is：0.001L, 0.010L, 0.100L, 1.000L, 0.001m³, 0.010m³, 0.100m³, 1.000m³.
