Flow Meter App Interface: Reading Digital Flow Transmitters Via Bluetooth and Wi-Fi
Quick Answer
Silver Instruments digital flow transmitters send live flow data to a phone or tablet over Bluetooth and Wi-Fi. The app shows flow rate, totalizer, temperature, pressure, and diagnostic alarms. This works with electromagnetic, vortex, Coriolis, oval gear, and thermal mass flow meters from DN15 to DN300. For a quote, send us your pipe size in DN, flow range, fluid, pressure in bar, and temperature in °C.
How Bluetooth Reading Works on a Flow Meter App
Bluetooth is the fastest way to pull data from a local flow meter. The Silver Instruments app scans for nearby devices within a 10 m range. Once paired, the app reads the digital transmitter every one second. Engineers use this for commissioning, troubleshooting, or spot checks at a pump skid or a filling line.
In practice, most customers start with the Bluetooth connection first. The setup takes under two minutes. You open the app, select the SIL-MAG electromagnetic flowmeter, and the app pulls the live flow rate in m3/h. A dairy plant in Thailand used this method to verify a CIP line without opening the control cabinet.
Wi-Fi Setup for Multi-Point Flow Monitoring
Wi-Fi works better when you need to read several meters from a control room. A flow transmitter with Wi-Fi joins the plant network. The app then shows multiple flow meters on one screen. This is useful for water treatment plants, boiler rooms, or tank farms.
One customer in Vietnam runs five SIL-VF vortex flow meters on a steam header. The app pulls total steam flow in kg/h from all five meters over Wi-Fi. The plant manager checks the data on a tablet from the office. No extra SCADA license is needed for basic trends and alarms.
Digital Flow Transmitters That Support the App
The app works with Silver Instruments flow meters that have a digital output board. Supported outputs include 4-20 mA HART, Modbus RTU, pulse, and Bluetooth Low Energy. Wi-Fi requires a module mounted inside the transmitter housing.
SIL-MAG electromagnetic flowmeter is for water, wastewater, and chemicals. It covers DN15 to DN300 with accuracy of ±0.5 percent. Lining options are PTFE or hard rubber.
SIL-VF vortex flowmeter is for steam, compressed air, and gas. It covers DN15 to DN200 and handles process temperature up to 250 °C.
SIL-CMF Coriolis mass flowmeter is for mass flow and density. Accuracy is ±0.2 percent for liquids and pressure rating i
SIL-OG oval gear flowmeter is for diesel, fuel oil, and lubricants. Flow range is 0.5 to 200 L/min.
What Engineers See on the App Screen
The main screen shows flow rate, total, temperature, and a real time trend. Users can switch units from m3/h to L/min to kg/h without changing transmitter settings. The diagnostic page shows signal strength, empty pipe detection, and sensor error codes. This saves time during startup and field service.
Most engineers skip the manual and go straight to the diagnostic page. We have seen this on customer sites many times. A water utility in the Philippines used the app to find an empty pipe alarm on a DN100 electromagnetic meter. The issue was a closed upstream valve, not a sensor failure.
Typical Installations Where the App Reduces Field Work
Bluetooth and Wi-Fi reading is not for every job. It helps most on skids, remote metering stations, and places where the meter is installed in a tight space. For a seawater desalination plant in Oman, the app allowed one technician to check four SIL-MAG meters without climbing into a pipe gallery.
For a paint manufacturer in Southeast Asia, the app read a SIL-CMF Coriolis meter during a solvent batching trial. The process engineer adjusted the batch from 800 kg/h to 950 kg/h based on live density and mass flow. No laptop was needed at the mixing deck.
FAQ
Does the app work with all Silver Instruments flow meters?
No. The app supports digital transmitters with Bluetooth Low Energy or a Wi-Fi module. Older meters with only pulse output cannot connect to the app.
Can I read multiple flow meters at the same time?
Yes. Wi-Fi mode supports multiple meters on one dashboard. Bluetooth mode connects to one meter at a time within 10 m.
What parameters does the app display?
Flow rate, totalizer, temperature, density for Coriolis meters, pressure if a sensor is wired in, and diagnostic alarms.
Is the app suitable for hazardous areas?
The phone or tablet is not rated for ATEX Zone 1. Use the app outside hazardous zones. The transmitter itself can remain in the hazardous area if it has the correct certification.
How do I get a price for a flow meter with Bluetooth or Wi-Fi?
