4000 Series Analog and Digital Flow Meters

TSI 4000 Series Analog and Digital Flow Meters are engineered for industrial manufacturing where repeatability, uptime, and integration matter. Production engineers use the 4000 Series to measure compressed air usage at stations, verify tool consumption, balance manifolds, and support end-of-line testing. The meters’ thermal mass sensing technology delivers fast response and stable readings across a wide dynamic range, helping teams evaluate both low leakage rates and high-flow events in the same setup.

Designed for integration, the 4000 Series offers analog voltage or current outputs and digital connectivity options compatible with common PLCs and data acquisition systems. This makes it simple to stream flow, temperature, and pressure readings into plant dashboards for traceability and trend analysis. Low pressure drop helps maintain process performance in applications such as leak testing, valve characterization, and component burn-in.

Key advantages for industrial manufacturing:

• Wide dynamic range for diverse stations and tools
• Low pressure drop that supports pneumatic system performance
• Fast response for transient events and leak checks
• Analog/digital outputs for PLC, SCADA, and DAQ systems
• Rugged design suitable for shop-floor environments

Common applications:

• End-of-line instrument verification and calibration checks
• Leak testing of valves, fittings, and subassemblies
• Monitoring compressed air consumption by tool and cell
• Gas delivery validation for production ovens and furnaces
• Fixture development and maintenance diagnostics

Selecting a model typically starts with the expected gas type, flow range, and required outputs. Many teams choose a range that covers normal operation with headroom for transient spikes. If you plan to log data to a central historian, confirm your preferred protocol and sampling rate. For portable tasks — such as spot checks across multiple lines — consider accessories that simplify quick connects and mounting.

When it comes to day-to-day use, technicians appreciate clear readouts, stable zeroing, and outputs that feed directly into existing controls. Whether you are improving energy visibility or qualifying a new assembly process, the 4000 Series helps teams make confident decisions with reliable flow data across industrial manufacturing operations.
