AsthmaMD Lung Performance Peak Flow Meter: Smartphone Application Connected Trackers and Industrial Flow Meter Alternatives
Quick Answer: The AsthmaMD peak flow meter is a portable medical device that measures peak expiratory flow for asthma patients. It sends readings to a smartphone app for trend tracking. For industrial buyers who need smartphone connected flow monitoring on water, steam, chemicals, or fuel, Silver Automation Instruments supplies electromagnetic, vortex, and Coriolis flow meters with 4-20 mA HART, Modbus, and data logger options.
Many engineers first see the AsthmaMD device and ask if it can measure process gas or liquid. The short answer is no. The AsthmaMD lung performance peak flow meter uses a mouthpiece and a small sensor. Its range is in liters per minute of exhaled air. It has no process connection, no flange, and no industrial signal output. A medical device cannot hold up against 10 bar water pressure or 150 degrees Celsius steam.
What Industrial Buyers Can Learn From Smartphone Connected Trackers
The AsthmaMD product shows one thing clearly. Remote data access is useful. Patients check their readings on a phone. Industrial operators need the same idea but at a larger scale. A water treatment plant in Vietnam wants flow data on a phone. A chemical batch plant in Indonesia wants totalized flow from a control room. A food and beverage line in Australia needs daily flow logs. Silver Instruments flow meters support these tasks with 4-20 mA HART and RS485 Modbus outputs. The signal can connect to a gateway or SCADA system. From there the data reaches a phone or a tablet.
Electromagnetic Flow Meter for Water and Wastewater
A DN15 electromagnetic flow meter handles conductive liquids from 0.1 m/s to 10 m/s. Standard liner is hard rubber or PTFE. Electrodes are 316L, Hastelloy, or titanium. Power is 220 V AC or 24 V DC. Output is 4-20 mA plus pulse. Accuracy is 0.5 percent of reading. This is a common choice for desalination plant feed water, cooling water, and wastewater discharge. If you need a seawater flow meter for desalination plant, specify titanium electrodes and PTFE liner. A customer in the Middle East used a DN100 electromagnetic flow meter on brine water with 35,000 mg/L salinity. The meter logged data to a paperless recorder. The 4-20 mA signal went to a PLC. Remote access was through Modbus RS485.
Vortex Flow Meter for Steam and Compressed Air
A vortex flow meter works on saturated steam, superheated steam, and compressed air. It is not a medical peak flow meter. It is built with 316 stainless steel body and a blunt body sensor. Typical pipe sizes are DN25 to DN200. Temperature range is up to 250 degrees Celsius for standard models. Pressure rating is up to 25 bar. A food processing plant in Thailand used a DN50 vortex flow meter on saturated steam at 8 bar. Flow range was 60 kg/h to 700 kg/h. The meter provided a 4-20 mA HART signal and a local display. The HART signal connected to a data logger for daily steam consumption tracking. That data was later accessed on a tablet over the plant network.
Coriolis Mass Flow Meter for Dosing and Low Flow
Some customers compare peak flow measurement to low flow liquid measurement. They are not the same. For low flow liquid, a Coriolis mass flow meter measures mass directly. It handles 0.1 kg/h to 500 kg/h depending on tube size. It works on diese
Oval Gear Flow Meter for Diesel and Fuel Oil
Oval gear flow meters fit small line sizes from DN4 to DN50. They measure diesel, fuel oil, and lubricants. A commercial marine operator in Australia used a DN10 oval gear flow meter for diesel consumption on a generator. Flow range was 1 L/h to 100 L/h. Output was pulse. The pulse signal connected to a local totalizer. The operator checked daily fuel use on a small display. For smartphone access, add a pulse to Modbus converter. This setup gives the same type of trend tracking for fuel without any connection to lung performance measurement.
Practical Selection Notes
Most engineers skip this part. Do not send an inquiry with only the words flow meter. Include your pipe size, media, flow range, pressure, temperature, and signal output. For example, a wastewater plant in Latin America sent this line: DN80, sludge, 0 to 60 m3/h, 4 bar, 30 degrees Celsius, 4-20 mA HART. That was enough for a quote in two days. For conductive liquids choose electromagnetic. For steam and gas choose vortex. For mass flow and density choose Coriolis. For clean oil choose oval gear.

FAQ
1. Is the AsthmaMD lung performance peak flow meter suitable for industrial gas or liquid measurement?
No. It is a medical device for respiratory therapy. It cannot handle process pressure, corrosive liquids, or high temperature steam.
2. Which Silver Instruments flow meters support smartphone connected data tracking?
Electromagnetic, vortex, ultrasonic, and Coriolis flow meters can connect to gateways or data loggers. Common outputs are 4-20 mA HART and RS485 Modbus.
3. What is the price of an industrial flow meter with remote tracking?
Price depends on pipe size, liner, process conditions, and output. A DN50 electromagnetic flow meter for clean water is a budget-friendly start. Send your parameters for a formal quotation.
4. Can Silver Instruments flow meters measure low flow liquid rates?
Yes. Coriolis mass flow meters measure mass flow from 0.1 kg/h. Oval gear flow meters measure diesel from 0.5 L/h. These are process instruments for liquid and gas, not peak expiratory flow meters.
5. How do I get a seawater flow meter for desalination plant?
Call us or send an email. Include salinity in mg/L or ppm, pipe size, pressure, temperature, and flow range. We will recommend the correct liner and electrode material.
