The technology of flowmeter products has progressively developed , and accurate flow measurement is no longer the only condition for customers to purchase flowmeters. After years of listening to customer feedback and understanding their needs, LORRIC has invested a lot of human resources and time in researching the functionality development of other information to solve the problems and pain points encountered by customers in the use of flowmeters. With the acquisition of this other information, customers do not need to spend more time and cost to write programs, and they can even further develop more complex functions based on this information.

 

What is environment and device diagnostics information?

 

We can find a variety of flowmeter products on the market, but the most basic core messages of flowmeters are instantaneous flow and cumulative flow. Generally, flow rate flow meters transmit instantaneous flow, and volumetric flow meters transmit cumulative flow, data other than the first two can also be obtained by the flow meter, and LORRIC classifies them as “other information”. LORRIC's flowmeter can monitor the flow direction, magnetic field interference, accumulated data of date, whether the flow exceeds the upper and lower limits and other related information through settings. There are sensors everywhere and in addition to important information, it is necessary to collect some information that is not directly related but helpful.

What is the environment and device diagnostics information included?

 

➤ Self-health:

To diagnose the condition of the flowmeter itself. Most of the information in Alarm A is related to the health of the machine itself, for example: magnetic field interference, abnormal fins, whether or not to monitor the screen, current loop disconnection, hardware failure, switch signal is on or off, battery level , paddle wheel health index, speed of sound, RSSI, Q, ToM/ToS....

 

Parameter setting value:

All parameters can be set, read, and transmitted back through RS485. The advantage is that the flowmeter can be remotely changed or the status of the flowmeter can be confirmed, for example: all the incorrect parameters, date, cumulative data for the date.

 

➤ Environmental Monitoring:

Environmental data at the location of the flowmeter, for example: temperature.

 

User-defined:

Most of the information in Alarm B is a user-defined situation, and the user can know whether the measured value is within the range. For example: whether the flow exceeds the upper and lower limits, and whether the cumulative flow exceeds the target.

How do users obtain the data of other information?

 

Direct Operation|

LORRIC's flow meters have provided most of the other information available to customers in the form of Alarm, and customers can grasp the machine and flow status from the user interface without writing additional programs.

Alarm and system Status Description

 

 

Switch Signals|

All Alarms can be set by setting the switch signal, and the switch signal can be transmitted to the external device when the Alarm occurs.

 

4-20mA|

Most of the other information will not be transmitted using 4-20mA communication.

 

RS485|

All parameters can be set, read, and the flowmeter can be changed remotely or the status of the flowmeter can be confirmed.

Modbus RTU Protocol

Communication Transmission Recommendations

 


Switch Signals 4-20mA RS485 Paper records

Instantaneous Flow

Upper and lower limits can be set, but relatively less accurate, less real-time, and more computationally intensive.

🏆

Lower delay for one-to-one dedicated lines.

Relatively long delay. Handwritten record.

Cumulative Flow

🏆

The most common is Pulse, which instantly returns the unit volume.

Less used.

Available in LORRIC flow meters, but less commonly used on the market.

The delay is relatively long, and there is a zero-return function.

There is a cumulative flow of dates provided.

Handwritten record. LORRIC provides a 14-day cumulative flow record.

Others

Some Alarms can output via Pulse, but they are limited because it can only select one output (or a large class of output). Less used.

🏆

You can get the most information, self-health, settings, environmental parameters.

One wiring can communicate with multiple units.

Handwritten record.

 

* 🏆 Indicates a more common usage than others.
