Frequency of data update

Due to frequent data updates for real time flow volume, data on the LED screen will update first, then data on the LCD screen. Therefore, they may have about 0.1 seconds updated time difference. between both data sets.If there are not many digits in the data, please use the LED screen for the main data.

Displayed digits on LED screen

Maximum 5 displayed digits are provided on the LED screen. If data digits exceed more than 5 digits, “FFFFF” will be displayed on the LED screen (please refer below image). At this time, for reading complete data, you can try to modify the units or see the 2nd row data on the LCD screen to confirm exact flow volume.

When the flow direction is reversed and the data is negative number, the 1st digit will be a minus sign with four remaining digits.

Environment and parameter check

3. This machine uses Modbus RTU protocol, communication parameter set-up as below.：

Advanced parameter setting (available since FW 2.3.0)

This setting provides 4 options.

ST stands for start bit, D0 ~ D7 are data bits, SP stands for stop bit.

OP and EP stands for Odd-parity and Even-parity respectively

This option controls the direction of the transfer and selects LSB or MSB first.

LSB first is typically used for Modbus RTU.

The figure below presents the difference with N-8-1 mode.

This setting controls the byte order of multi-byte data. This setting solely interacts with the byte order of replied data. The byte format of register address and length in the commands still conform to the examples provided by manual. The figure below presents the byte order for when converting number 1000 in IEEE-754 format.

Example

The command below requests instantaneous flow speed (abbreviated to FS) and totalized flow rate ( abbreviated to TF) from the device.

According to the Modbus protocol, the address and length of registers both consist of two bytes. And as the figure above shows, this option does not affect the byte order of the command. It only changes the order of replied data.

Environment and Parameter Check

Parameter setup

Please refer to the ​

Set-up steps as below:

1. Please set up the 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.

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.

Plastic (PVC, PP, PVDF) T-connector

PulseV2

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.
