Leading Open Channel Flow Meter Manufacturers

Open channel: a flow of fluid where there is one free surface present, and the only pressure on it comes from gravity. Read More…

Open Channel Flow Meter Open channel flow meters deal with free flowing, or free gravity flowing, open channels. The flowing liquid of these channels have a top surface open to the air. The cross-section of their flow is based only on the shape of the shape of the lower side of the channel through which they flow.

Sierra manufacturers high performance mass flow meters and controllers for nearly any gas, liquid or steam. Customers choose Sierra when they need an accurate and repeatable flow measurement, short delivery lead times, expert flow advice and long term support. When it matters, choose Sierra.

There are many different types of open channel flow, depending on the environment in which they are found. For example, some have no changes in the depth of liquid where others have a constant, unsteady flow.

Open channel flow meters monitor the relationship between the depth of the liquid and the flow rate. In contrast, most other flowmeters use mass or volumetric data to determine flow rate. In order to do their work, open channel flow meters typically use ultrasonic transducers, pressure sensors, shaft encoders, or special radars that can function in a free surface.

Other types of open channel flow measurement include: area/velocity flow measurement, level to flow measurement (measured at a designated point behind a weir, in a flume, or other hydraulic pumps, using various secondary devices), dye testing (when operators add a known amount of dye (or salt) per unit time to a flow stream. After complete mixing, they measure the concentration; the dilution rate equals the flow rates.), and Acoustic Doppler velocimetry (used to record instantaneous velocity components at a single point with a relatively high frequency, uses the Doppler shift effect to measure the velocity of particles in a remote sampling volume).

Open channel flow meters work where traditional flow meters cannot. Specifically, traditional flow meters cannot work where the top surface of a liquid is exposed to the open air. Most commonly, open channel flow meters are used in water and wastewater industries, as water and wastewater are by and large the most common liquids found in open channel flows. However, they are also popular anywhere open channel flows are found. They can even measure flow in rivers.

Regardless of your exact application, if you seek an open channel flow meter, you need to find a supplier that is knowledgeable on the subject, skilled, and reliable. Find that supplier by browsing the websites of those flow meter manufacturers and distributors that we have listed on our website, and reaching out to one or more of them with your specifications.

Coriolis Flow Meters

Coriolis Flow Meters

A Coriolis flow meter measures mass by the inertia of a liquid or gas flowing through a vibrating tube that is equipped with a set of sensors at the inlets and outlets of the meter. The increased movement of the flow produces measurable oscillation that is proportional to the mass...

Flow Switches

Piston Type Flow Switch

A flow switch is a device that measures the flow rate and liquid pressure within a duct, loop, or system. Flow sensor and flow indication are other names for this switch. The primary purpose of a flow switch is to continually...

Level Switches

Level Switch

A level switch is an electrical or mechanical method for measuring the level of a liquid, powder, or granule material. It is designed to activate an alarm if the material level in a container passes a predetermined height or depth...

Magnetic Flow Meters

Magnetic Flow Meters

A magnetic flow meter is a volumetric flow meter that uses electrodes connected to the liquid flow to measure the velocity of fluids in a tube or pipe. The unique design of magnetic flow meters allows them to take their readings without the need for any moving parts...

Mass Flow Meters

Mass Flow Meters

A mass flow meter is a way of measuring the volume or mass of a gas or liquid passing through a system at a specific point in the flow system. They are used to measure linear, nonlinear, mass, and volumetric flow rates...

Ultrasonic Flow Meters

Ultrasonic Flow Meters

An ultrasonic flow meter measures the flow of a liquid or gas by sending ultrasonic waves across a pipe, containing the flow in the direction of the flow and in the opposite direction of the flow. The ultrasonic waves and the velocity of...
