Flowread Flow Meter Interface: Software Integration and Real-Time Data Logging for Industrial Lines
Quick Answer: Flowread is the Silver Instruments software interface for reading flow meter data on production lines. It supports 4-20 mA, HART, Modbus RTU and pulse inputs. Engineers use it for real-time trending, CSV export and alarm handling without changing the main PLC program.
Here is the thing. Many flow meters on site already send 4-20 mA or Modbus signals. The missing part is often a simple logging tool that plant teams can read. Flowread fills that gap. Flowread runs on a Windows panel PC or a site laptop. Flowread stores data locally and can push values to a plant SCADA over Modbus TCP.
What Flowread Does on an Industrial Line
Flowread collects rate, totalised volume, pressure and temperature from field instruments. The log file includes date, time, tag name, value and alarm status. A water treatment plant in Indonesia uses Flowread with DN80 electromagnetic flow meters on raw water inlet lines. The operator checks daily cubic metres in one window instead of walking to three separate panels.
Log intervals are selectable. Most plants use 1, 5 or 10 seconds. Flowread can store more than 10 years of trend data on a 256 GB industrial SSD. Export to CSV is a one click action. The file name follows site name plus date, so a shift report is easy to find.
Supported Flow Meter Types and Signal Inputs
Flowread is not tied to one meter brand. It reads Silver Instruments electromagnetic flow meters, Coriolis mass flow meters, vortex flow meters, oval gear flow meters and thermal mass flow meters. Common input types include 4-20 mA with HART, Modbus RTU over RS485, open collector pulse and PT100 temperature.
For conductive liquids such as water, wastewater, chemicals and food products, use an electromagnetic flow meter. Silver Instruments offers sizes from DN15 to DN600. A typical setup sends 4-20 mA for flow rate and pulse for total. Flowread logs both signals and shows deviation if the two values do not match.
For oils, solvents, syrups and compressed gases, a Coriolis mass flow meter gives mass flow in kg/h. Flowread can read mass flow, density and temperature over HART or Modbus. A chemical plant in Nigeria uses this setup on a solvent blending line. The team logs density every 5 seconds to detect batch quality drift.
Software Integration for SCADA and Plant Systems
Flowread works beside an existing PLC or SCADA. Flowread does not ask for a full control system replacement. The software reads the same 4-20 mA signal in parallel or reads Modbus registers from the flow meter. For a larger network, Flowread can publish data over Modbus TCP to a plant historian or OPC UA client.
In practice, we see two common installations. The first is a standalone PC in a control room that logs data for a single production line. The second is a plant wide system with 15 to 40 meters connected through RS485. Both use the same Flowread software licence.
Real-Time Data Logging and Export
Flowread time stamps every record with millisecond resolution. The shortest log period is 1 second. For fast filling lines, use a pulse input from an
Alarm rules are simple. You set a low flow value, a high flow value, a pressure limit or a temperature limit. When the reading crosses the setpoint, Flowread writes an alarm tag. The alarm list is visible on screen and can be sent by email. A beverage plant in Vietnam uses a low flow alarm on 12 filling lines to detect blocked nozzles before a batch is lost.
Typical Project Examples
A desalination plant in Saudi Arabia uses two DN200 electromagnetic flow meters on seawater intake and brine discharge. Flowread logs both flows at 5 second intervals. The operator compares the two values to calculate recovery ratio for the shift report.
A paint manufacturer in Southeast Asia uses a DN25 oval gear flow meter on a solvent dosing line. Flowread reads the pulse output and displays batch volume in litres. The batch stops at 750 L. The system logs every batch with date, time and operator tag.
A food processing site in Mexico uses a thermal mass flow meter on a natural gas line. Flowread records Nm3/h every 10 seconds. The plant exports a monthly CSV file for energy reporting.
How to Order a Flowread Package
Send us your process data. Include pressure in bar, temperature in °C, pipe size in DN and flow range. We recommend the meter type and the correct Flowread input module. For hazardous areas, specify ATEX Zone 1 or Zone 2. For high viscosity fluids above 200 cP, we size a Coriolis meter with low pressure drop. For sanitary food lines, ask for tri clamp connections. Silver Automation Instruments supplies the meter, signal cable, USB converter and Flowread software in one package.

FAQ: Flowread Flow Meter Interface
What flow meter signals can Flowread accept?
Flowread accepts 4-20 mA, 4-20 mA with HART, Modbus RTU over RS485, open collector pulse and PT100 temperature. A USB data collector is included for pulse and 4-20 mA inputs.
Can Flowread export data to CSV or Excel?
Yes. Flowread exports CSV files for any selected period. The file opens in Excel, Google Sheets or plant reporting software. You can also export alarm logs.
Does Flowread work with an existing PLC?
Yes. Flowread reads the same analog signal in parallel. Flowread does not interrupt the PLC loop. You can also read Modbus registers directly from the flow meter.
What is the shortest log interval?
The shortest interval is 1 second. For pulse based batch totalising, Flowread counts the pulse input directly with no scan delay.
Can Flowread read HART and Modbus at the same time?
Yes. A typical setup reads 4-20 mA plus HART for diagnostics and Modbus RTU for total and density. Flowread merges the values into one data record.
