Peak Flow Meter Image: Detailed Visual Aid Mapping Scales, Pointers, and Mouthpiece Medical Parts
Quick Answer: This image shows a medical peak flow meter, not an industrial process meter. The scales, pointers, and mouthpiece are parts of a handheld asthma monitoring device. Silver Automation Instruments does not sell this medical tool. We supply electromagnetic, vortex, Coriolis, ultrasonic, thermal mass, and oval gear flow meters for process industries.
Most engineers skip this part when they see the words peak flow meter and assume gas flow measurement. But the scales and pointers on this image are marked in liters per minute for human breath. The mouthpiece is a plastic part for a patient to exhale into. These parts do not match pipe threads, flanges, or 4-20 mA HART outputs.
What the Medical Image Actually Shows
The image of a peak flow meter with detailed visual aid mapping scales, pointers, and mouthpiece medical parts helps a nurse or doctor explain asthma monitoring. The scale usually reads from 60 to 800 liters per minute. The pointer stays where the patient reaches peak exhale flow. The mouthpiece is a plastic or cardboard tube that touches the lips.
Industrial users sometimes search this image because they need a flow meter for ventilation, aeration, or flue gas. A customer in Vietnam asked us about this exact image last year. He needed a low cost device for compressed air at 7 bar. But a medical peak flow meter cannot handle pipe pressure. It has no current output, no totalizer, no RS485, and no explosion proof housing.
Scales and Pointers on a Medical Meter vs an Industrial Meter
The pointer on a medical peak flow meter moves by air pressure from the lungs. It gives one peak reading. There is no continuous output, no data logging, and no temperature compensation. Industrial flow meters from Silver Automation Instruments give a live signal. You can get 4-20 mA HART, pulse, RS485, or Modbus. The local display on our electromagnetic or vortex meter shows flow rate in m³/h, total flow in liters, and diagnostic codes.
If you need a meter for compressed air, a vortex flow meter fits your pipe from DN15 to DN200. It works up to 350 °C and handles pressure up to PN40. Add a pressure transmitter if you need standard volume flow. Most engineers skip this part and only send flow range. But pressure and temperature change gas density. You need all three values for useful data.
Mouthpiece Parts Are Not Pipe Connections
The mouthpiece in this peak flow meter image is a disposable medical component. It is not a process connection. Do not glue it, weld it, or clamp it to a pipe. Industrial flow meters use standard connections like ANSI 150 flanges, DIN PN16 flanges, Tri-Clamp for food and beverage, or NPT for small lines.
Because the mouthpiece is plastic, it can deform in hot process fluids or aggressive chemicals. We have seen this on customer sites many times. A paint manufacturer in Southeast Asia bought a cheap plastic device for solvent flow at 80 °C and 20 bar. The meter failed in two days. They replaced it with a Coriolis mass flow meter from our Nanjing factory. The new meter measured solvent flow at 100 to 800 kg/h for two years without drift.
Industrial Flow Meter Options from Silver Automation Instruments
Silver Automation Instruments supplies process flow meters and pressure transmitte
Electromagnetic flow meter for conductive liquids like tap water, wastewater, acid, and slurry. It works from DN10 to DN1200, with PTFE or polyurethane liner and 316L electrodes. Output options are 4-20 mA HART, pulse, RS485, or Modbus.
Vortex flow meter for steam, compressed air, and natural gas. It covers DN15 to DN300, pressure up to PN40, temperature up to 350 °C. The sensor is not affected by vibration after proper installation.
Coriolis mass flow meter for diesel, oils, syrups, and chemical dosing. It measures mass flow, density, and temperature in one device. Accuracy is up to 0.1 percent of reading.
Ultrasonic flow meter for large water pipes and seawater desalination. Clamp on and inline types are available. It is good for DN25 to DN1200 and handles pipe pressure up to PN16.
Thermal mass flow meter for biogas, aeration air, and flare gas. It gives direct mass flow in kg/h or Nm³/h. The insertion probe is easy to install in large ducts.
Oval gear flow meter for diesel, fuel oil, and lubricants. It works with viscosity from 1 cP to 1000 cP. Maximum pressure is 40 bar and temperature up to 150 °C.
We also manufacture pressure transmitters and paperless recorders. These devices complete a monitoring loop with the flow meter. A 4-20 mA HART signal from a pressure transmitter goes directly to the recorder. This keeps a long term trend of pressure and flow on one screen.
We ship to Southeast Asia, Oceania, Latin America, Africa, and the Middle East. A seawater desalination plant in Saudi Arabia ordered 12 electromagnetic flow meters from us last quarter. The pipes were DN200, 16 bar, 35 °C, with 4-20 mA HART and RS485. The meters were shipped from Nanjing in 9 days.
How to Get a Quote for the Right Flow Meter
Do not send a photo of a medical peak flow meter for a process application. Instead send us your pressure (bar), temperature (°C), pipe size (DN), and flow range. Also tell us the fluid type, conductivity for electromagnetic meters, viscosity for oval gear meters, and hazardous area zone if needed.

FAQ
Is this peak flow meter image relevant to industrial flow measurement?
No. It is a handheld medical device for asthma patients. It does not measure process fluid flow in pipes.
Can I use a medical peak flow meter for compressed air?
No. The mouthpiece and plastic body cannot handle pipe pressure above a few mbar. You need a vortex flow meter or a thermal mass flow meter.
What industrial flow meter is best for compressed air?
A vortex flow meter with DN15 to DN100, 4-20 mA HART, pressure and temperature compensation works well for compressed air lines.
Do you sell medical peak flow meters?
No. Silver Automation Instruments focuses on industrial process instruments only. We do not supply medical devices.
What information do you need to quote a flow meter?
Fluid, pressure in bar, temperature in °C, pipe size in DN, flow range, output signal, and hazardous area if any.
