Flow Meter Asthma Chart Log: Tracking Daily Peak Expiratory Flow Rates at Home
Quick Answer: A home peak flow meter for an asthma chart log is a medical device that measures exhaled air in liters per minute. Silver Automation Instruments does not sell medical peak flow meters. We supply industrial flow meters for process lines, water treatment, gas, and chemical plants.
What the Asthma Chart Log Measures
A typical asthma chart log tracks daily peak expiratory flow rates at home. The patient blows into a handheld peak flow meter. The reading is in L/min. Doctors use the log to adjust medication. This device is not built for industrial piping.
Many families keep a chart next to the bed. They record morning and evening values. That data shows trends in lung function. It works as a simple time series.
Industrial Flow Meter Requirements Are Different
Industrial flow meters handle harsher conditions. A chemical plant may need a Coriolis mass flow meter for 0 to 5000 kg/h flow range. Pipe size may be DN15 or DN50. Output is 4-20 mA HART. The housing may need ATEX Zone 1 certification. That is a different world from a home asthma chart log.
We have seen customer sites where a water line carries 200 m3/h at 6 bar. The meter must survive wet conditions and long cable runs. A handheld peak flow meter cannot measure that.
Product Choices for Process Engineers
For water and wastewater, electromagnetic flow meters work well. A desalination plant in the Middle East used DN200 electromagnetic meters on seawater intake. Conductivity was above 1000 µS/cm. The meter body had no moving parts.
For edible oil or diesel, an oval gear flow meter may be appropriate. Viscosity can range from 10 cP to 1000 cP. Positive displacement meters handle that better than turbine meters.
For gas flow, thermal mass flow meters give direct mass reading. For steam, vortex flow meters are common. We do not sell medical devices for home use.
Daily Logs Are Useful in Industrial Flow Metering Too
A home asthma chart log is a simple time series. In a process plant, a paperless recorder does the same job with more channels. It logs flow rate, temperature, pressure, and total. We often recommend a paperless recorder for batch traceability or custody transfer.
A customer in Mexico asked us for a paperless recorder to log flow data from a vortex meter and a PT100. The recorder sampled every 1 second and stored data on an SD card. They later exported CSV files for their daily report.
How to Choose Between Meter Types
Start with the fluid. For clean water, electromagnetic is common. For diesel, an oval gear flow meter works because diesel has low viscosity around 2 to 6 cP. For gas, thermal mass or vortex. For mass balance in food and beverage, Coriolis is better.
Most engineers skip this part because the process data is not ready. In practice, collect a sample data sheet before asking for price. The data sheet should include pipe size, flow range, pressure, temperature, and output signal.
Specific Customer Scenarios
Last year a customer in Vietnam a
A water utility in Australia needed a seawater flow meter for a desalination plant. We recommended an electromagnetic flow meter with PT100 temperature sensor and local display. Conductivity was above 1000 µS/cm. They needed no moving parts because of barnacle growth.
Food and Beverage Applications
A juice plant in Nigeria needed a flow meter for fruit pulp with conductivity around 800 µS/cm. Pipe size was DN40. Flow range was 0 to 20 m3/h. We recommended an electromagnetic flow meter with sanitary connection and 4-20 mA HART output. The plant used a paperless recorder to store daily totals.
For chocolate or honey, viscosity is high. A Coriolis mass flow meter or oval gear meter is a better fit. These fluids do not behave like water. In practice, the process engineer should measure viscosity at the actual operating temperature.
Why Some Buyers Confuse Medical Flow Meters and Industrial Flow Meters
The word flow meter covers many products. A home peak flow meter is small, manual, and low cost. An industrial flow meter is inline, powered, and calibrated. Search engines sometimes mix these terms. In practice, you should state the fluid, flow range, pipe size, and output signal.
Some buyers send us a request for a flow meter without details. They might need a rotameter for a laboratory or a peak flow meter for asthma. We cannot quote without fluid and flow rate. The more detail you give, the faster we can help.
FAQ
Question: Does Silver Automation Instruments sell peak flow meters for asthma?
Answer: No. We supply industrial flow meters only. For a home asthma chart log you need a medical device from a pharmacy or medical supplier.
Question: What is the difference between L/min and m3/h?
Answer: A peak flow meter reads L/min. Industrial flow meters usually use m3/h, kg/h, or L/min depending on the process. We can advise on unit conversion.
Question: Which flow meter is best for wastewater?
Answer: Electromagnetic flow meters work well for conductive fluids. You need conductivity above 5 µS/cm. Provide pipe size and flow range.
Question: Can I use an industrial flow meter for compressed air?
Answer: Yes. Thermal mass flow meters or vortex flow meters are common. Give us pressure, temperature, and pipe size.
Question: What details do I need for a quote?
Answer: Fluid name, pressure in bar, temperature in °C, pipe size in DN, flow range, output signal, and hazardous area certification if needed.
