Please see the page of monitoring screen.

Cable wiring

Please see the page of mechanical and electrical installation.​

Parameter setup

Please refer to the parameter set-up page.​

Set-up steps as below:

1. Please set up the basic parameters first.

2. Connect cable first according to the cable wiring instructions on this page.

3. Set up parameter E01 for selecting NC(Normal Close) or NO(Normal Open) when there is no signal.

4. Set up parameter E02 for specifying output signal content.

   1. For selecting “pulse output”

      1. Use E03 to confirm each pulse width.

      2. Use F03 to simulate specific pulse output frequency at OCT for testing with external devices.

   2. For selecting “pulsev2”

      1. Use E03 to confirm each pulse width.

      2. Use E14 to determine each pulse capacity.

      3. Use F03 to simulate specific pulse output frequency at OCT for testing with external devices.

   3. For selecting “out of range flow volume notice”.

      1. Use D04 to turn on the alarm.

      2. Use D05 D06 for specifying normal flow range.

      3. Use D07 for specifying hysteresis range percentage. D07 is a positive value, it means the ranges single must exceed in order to disable the alarm.

      4. Set up F01 and F02 for simulate flow volume and go back to the monitoring screen to confirm the alarm works

      5. Turn off the simulation mode.

   4. For selecting “Total Ala.” (“Inform of over total target”)

      1. Use D08 to turn off alarm

      2. Use D09 for specifying notification conditions. "Larger Than" is for positive flow direction, "Less Than" is for negative flow direction.

      3. Use D10 for specifying total target, positive number is for positive flow, negative number is for negative flow.

      4. Set up F01 and F02 to simulate flow volume and go back to the monitoring screen to confirm the alarm works.

      5. Turn off the simulation mode.

5. Go back to the monitoring screen, finish.

Pulse output

Pulse output is based on the frequency of the paddle wheel’s revolutions. A pulse will be sent by every 180° revolution. At a flow rate of 10m/s, the maximum frequency will not exceed 300 Hz. Since the data processing technology of LORRIC is not used, it is recommended to use it in an environment with lower accuracy requirements. To calculate the total flow volumes for a certain period of time, count the number of pulse signals received then divided by the corresponding proportion this manual provides. Proportion is defined by pipe size and material. Please refer to the following information.

PulseV2

This function has been tested in limited scenarios, it is still in the public testing stage. Please test and carefully evaluate the applicability before using it

PulseV2 is an exclusive function developed by LORRIC based on patented AxelSense technology. The unique algorithm allows the users to select a fixed volume, and the device will output a pulse every time a unit volume flows. The device can also intelligently correct error at low flow rate, making smaller pulse data error. Compared with the traditional pulse output, which directly outputs the revolutions of paddle wheel, every time the blade sweeps over the Sensor and outputs a pulse. “PulseV2” has two advantages: 1. The user can easily understand how to set up the controller. 2. Error of low flow rate is smaller.
