A few missed pulses here and there leads to massive inaccuracies. To accurately read and totalize flow rate, a subsystem must be used that has been specifically designed to do just that, the EZO-Flow circuit is the solution.

Connect your flow sensor to this circuit to create a workable signal for your microprocessor using UART or I2C protocol.

Reading the signal from a flow meter is easy; until you actually try and do it. A few missed pulses here and there leads to massive inaccuracies over a relatively short time. To accurately read and totalize flow rate, a subsystem must be used that has been specifically designed to do just that (hint don’t use your CPU to totalize flow; it’s busy doing other things).

The EZO-Flow can be used with your own pulsed D.C. flow meter, or it can be connected to one of the flow meters we offer.

It may happen that you want to return an order. Because the product does not suit you, maybe there is another reason why you would not want the order. Whatever the reason, you have the right to cancel your order up to 14 days after receipt without giving a reason.

After cancellation you have 14 days to return your product. You will then be credited 85% order amount excluding shipping. For more information click the following link: /pages/shipping-and-returns
