What device measures velocity for low flow?

Pitot-tube is a device used for measuring the velocity of flow at any point in a pipe or a channel.

What is minimum flow rate in water meter?

The operating flow rates of a water meter are defined as follows: Q1, the minimum flow rate is the minimum value at which the meter operates without exceeding the maximum permissible error value (ɛ1). Q2, the transitional flow rate is the value between the constant or nominal flow rate and the minimum flow rate.

Which meter is used for low volume flow measurement?

You can buy low volume fuel flow meter from us with flow as low as 0.6 L/ h (10 ml/min) from us. Which flow metre is used for low volume flow Measurement purpose? We recommend gear flow meter to be used as low volume flow meter. It is a kind of volumetric flow meter, not a mass flow meter.

Which is the device for measuring flow velocity?

A flow meter (or flow sensor) is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas.

What are the various devices used to measure velocity of flow?
