Process Control Instruments for Accurate Liquid Flow Measurement

This series includes flow totalizers, paper chart recorders and paperless data loggers for industrial process monitoring. It calculates cumulative flow, records real-time temperature, pressure and flow data, with local display and data storage functions. Supporting multiple signal inputs, these devices deliver reliable data tracking for chemical, energy and water treatment production lines.

Types of Process Control Instruments

Flow Totalizers

Flow totalizers match various flowmeters to calculate instantaneous and cumulative flow of liquid and gas. With digital local display and standard signal output, they support flow unit conversion and batch accumulation, widely used for metering statistics in chemical, water supply and energy pipelines.

Process Control Instruments Engineered for High Accuracy and Long-Term Reliability

Precision Measurement Core for Stable Process Data

Our flow totalizers, chart recorders and paperless loggers adopt high-precision signal acquisition chips to reduce data deviation. They accurately capture flow, pressure and temperature signals, ensuring consistent measuring accuracy under long-running industrial production conditions.

Dual Recording Solutions Meet Diverse Archiving Demands

We supply both paper chart recorders for physical paper archives and paperless data loggers for digital storage. Paperless loggers support USB data export and curve review, while chart recorders offer direct visual paper traces to satisfy different factory audit and traceability standards.

Wide Compatibility with All Flow & Sensing Devices

All process instruments support mainstream pulse, 4-20mA and multi-channel analog input signals, seamlessly pairing with liquid, gas flowmeters, pressure and temperature transmitters. They integrate easily into existing automation systems without extra signal conversion modules.

Industrial-Grade Hardware Ensures Long Service Lifespan

The whole series adopts dust-proof, anti-interference circuit design and robust shell structure, resisting voltage fluctuation, electromagnetic interference and mild damp environments. Low component wear lowers maintenance frequency and extends continuous service life for on-site equipment.

Why Process Control Instruments Are Essential for Efficient Process Automation

Deliver Real-Time Accurate Process Data as Automation Foundation

Flow totalizers, recorders and data loggers continuously collect flow, temperature and pressure signals. They convert raw sensor signals into readable standardized data, which PLC and control systems rely on to execute automatic adjustment and closed-loop production control.
Realize Full-Cycle Data Traceability for Quality Compliance

Paper chart recorders leave visible physical records, while paperless loggers store massive digital historical data. Complete parameter archives support factory quality audits, batch tracking and fault analysis, helping enterprises meet industrial production supervision standards.
Cut Manual Labor and Lower Human Operation Errors

These instruments automatically complete flow accumulation, parameter recording and curve drawing instead of manual reading and logging. They reduce repetitive manual work, avoid artificial reading deviations, and greatly improve overall workshop operation efficiency.
Support Early Risk Warning to Reduce Production Loss

Most models equip over-limit alarm output functions. When process values exceed safe thresholds, they send signals to trigger interlock protection, timely preventing overflow, overpressure or overheating failures and minimizing unexpected downtime and material waste.
Ensure Flexible Compatibility with Diverse Automated Production Lines

Universal pulse, 4-20mA and RS485 signal interfaces allow seamless matching with flowmeters, transmitters and control systems. They adapt to chemical, water treatment, energy and food industries, realizing rapid transformation of new or old automation equipment.
