How to choose the appropriate flow meter for your application?

As we have all seen, there are various kinds of flow meters deriving from 10+ theories of flow measurement that leaves clients in a limbo as to what product can meet their requirements. LORRIC, as a professional developer and manufacturer works closely with end users to closely understand what their needs and problems are. Therefore, we are deeply aware of what issues and questions clients might have and we’re able to provide consulting and professional suggestions to prospective users.


Generally, prior to choosing a flow meter, LORRIC suggests you consider 5 points. Please see those 5 points below:



There are a myriad of flowmeters at every price point. Allocating the right amount of budget is important before deciding what flowmeter to purchase.


Could you afford the cost of cutting into the pipe when installing?

The main cost associated with cutting into the pipe is loss of productivity due to maintenance turnaround and shutdowns. However, a clear benefit is the lower price point for flow meters that require cutting into the pipe compared to the higher priced non-invasive meters like the ultrasonic. Therefore, users must take that into account when deciding what flowmeter justifies their costs.


Do you need a flow meter with flow sight?

In some factories, the liquid flow in a pipe could possibly generate crystallisation and precipitation. This makes it crucial for users to monitor the liquid flow inside of the pipe. Adding a flow meter with flow sight will help reduce costs because it will make purchasing additional sight tube products unnecessary.。


Do you need flow meters with electronic signal output?

If users are replacing equipment with instrumentation fit for industry 4.0. As an example, integrating real-time flow measurement data to their devices. Then, a signal output connection is imperative. LORRIC’s paddlewheel and ultrasonic offers Modbus RS485, 4-20mA and pulse output.


Monitoring Flow Speed Range

 Each kind of flow meter has its own monitoring range for flow speed. In order to choose the right flow meter, users must figure out the flow speed range of the liquids they are measuring.


LORRIC believes that by taking the above 5 points into consideration users will be able to get the best flow meter that fits their requirements.


 We took three of the most common flowmeters: variable area, ultrasonic and paddlewheel as examples to distinguish them by the above 5 points. We hope this will help new users to choose the right flowmeter.
