Can it control the flow to a specified amount with this flowmeter?

Thank you for this good information.
Can I control the flow to a specified amount with this flowmeter as well?
Or is this item just to measure the flow, and I would have to regulate the flow through valving upstream of it?

1. Our flowmeter can only measure.
2. Yes, you also need valves to control and regulate the flow.

Can you offer flow meter options for my application?

I'm actually looking to measure around 0.7 L/min with 1-2% accuracy.
Is there any flowmeter option you offer for this application?

You can choose our ATO-MF4000, the range is 0~2L/min, please refer to the link: https://www.ato.com/small-gas-mass-flow-meter
But it measures around 0.7 L/min with an accuracy of 2.1%, is it acceptable to you?

I want to ask some questions about mass flow meters.

Okay. I was roughly checking the manual, maybe I asked more questions. I want to measure variable flow of gas. Is it possible to sample flows like in each minute and store data? You mentioned about 485 communication, maybe you highlight me on this. Okay, I shall be waiting for you technical details.

SKU: ATO-FLOW-MF5700
See specs, price, and you can order online by credit card at: https://www.ato.com/digital-gas-flow-meter
For measuring variable flow of gas, it will not affect the reading of the meter as long as it does not exceed its maximum flow range, and you can store data via 485 communication.
About 485 communication, it also needs your controller or computer to support 485 communication, and you can refer to the communication protocol in the manual.

Ideal small gas mass flow meter

This is an ideal small gas mass flow meter for measuring gas flow. I used it to measure the flow rate of a gas pipe with a diameter of 3mm. The measurement result is very accurate and it is a reliable product.
