Peak flow meters provide many uses for patients with asthma or lung disorders. They help determine if a patient needs to adjust his or her daily medication or can show that patients may need to change the way they are using their medicines. Because peak flow meters may help identify causes of asthma at work, home or play, they may also help parents to determine what might be triggering their child's asthma. Peak flow meters can also be used during an asthma episode.

These meters can help determine the severity of the episode, decide when to use rescue medication, and decide when to seek emergency care. They are small devices that are easy to put in a pocket or purse if needed. Translucent plastic is widely used because it allows the user to quickly make a clear reading and is durable.

Peak flow meters are available in a variety of sizes and shapes; however, all peak flow meters work a similar way. A mouthpiece is attached to a plastic tube with a scale and slider or pointer mechanism at the opposite end. They are read similarly to flow indicators. A user inhales deeply and expels as much air from his or her lungs as possible into the flow meter; these devices are self-powered, unlike electromagnetic flowmeters .

The force is the peak expiratory flow (PEF) and is frequently measured in liters per minute. The pointer moves in accordance with the volume of air exhaled and the reading is recorded. Peak flow meters rates may be tracked and charted during the course of a day to help monitor asthma. A "normal" peak flow meters rate is based on a person's age, height, sex, and race. A standardized "normal" may be obtained from a chart comparing the patient with a population without breathing problems. Each patient has his or her own "normal" peak flow meters rate.

Three zones of measurement are commonly used to interpret peak flow meters rates, based on level of danger. These three zones are typically classified as green, yellow, and red, similar to the meaning of traffic lights. Peak flow meters come in two ranges of measurement, low and standard. Low range peak flow meters are for small children, and a standard range meter is for older children, teenagers, and adults.

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...
