Description

The paperless recorder is an electronic instrument that samples industrial process signals through a 24-bit ADC, applies the standard linearization (IEC 60584 for thermocouples, Callendar-Van Dusen for RTDs, scaled engineering units for 4–20 mA), and writes the result to internal flash storage. Up to 64 channels per chassis with 3-way galvanic isolation between channel-channel, channel-power, and channel-comms.

Front-panel touchscreen for live trend, alarm history and configuration. Trend stored as a tamper-evident binary file plus CSV; signed-PDF export available for 21 CFR Part 11 batch reporting.

  • Custody flow measurement — F3000X with density/temperature compensation, batch totalizer.

What is a paperless recorder?

The paperless recorder is a stand-alone process data logger that replaces a strip-chart or circular recorder. Where the older instrument drew an ink trace on paper as the chart wheel rotated, the paperless recorder samples the same inputs at 100 ms–1 s, displays the trend on a touchscreen, and stores the values to internal flash for compliance and audit retrieval.

The recorded data are written as a tamper-evident binary file plus a CSV companion. The binary is the legally defensible record (signed checksum); the CSV is the convenience export for spreadsheets. Trend data and configuration changes are timestamped against an NTP-synced clock so the audit trail satisfies FDA 21 CFR Part 11 and AMS 2750E requirements for pharmaceutical and aerospace heat-treat work.

How does a paperless recorder work?

The paperless recorder is built around an industrial microprocessor, a 24-bit sigma-delta ADC, RAM and flash storage, and a touchscreen front. Each input channel is multiplexed through the ADC at the configured sampling rate (typical: 1 s per channel for compliance work, 100–200 ms for combustion and compressor monitoring).

The microprocessor applies the appropriate linearization curve (IEC 60584-1 for thermocouples, Callendar-Van Dusen for Pt100/Pt1000 RTDs, scaled engineering units for 4–20 mA inputs), computes alarm logic (HiHi / Hi / Lo / LoLo with deadband and on-delay), and writes the storage-interval-averaged value to internal flash. On alarm, a burst-capture routine stores the full sampling-rate data around the event so post-incident analysis sees the raw waveform.

Q&A

Is a paperless recorder the same as a data logger?

Closely related but not identical. A data logger is typically a small standalone unit with battery power and limited inputs; a paperless recorder is panel-mounted, plant-powered, with a touchscreen, more channels, built-in alarms, and SCADA integration.

How many channels do I need for a typical heat-treat furnace?

AMS 2750E TUS (temperature uniformity survey) calls for 9 thermocouples on a 60-225 cubic-foot furnace plus the control thermocouple – 10 channels active. Allow one card-slot of headroom and pick a 16-channel R7100 or R7600.

What protocols are available for SCADA integration?

Modbus TCP slave is standard. OPC UA server, MQTT publisher, and Modbus RTU (RS-485) are option keys. USB host accepts a flash drive for ad-hoc CSV export; Ethernet web server allows browser-based trend download.

Do paperless recorders need calibration?

Yes – annually for compliance work, every 2 years for non-critical applications. Calibration is per channel and includes the cold-junction reference for thermocouple inputs. Field calibrators (Fluke 754, Ametek MC) inject known signals and write the verification result to the audit trail.

What if I lose power mid-batch?

Internal flash memory is non-volatile, so the recorded data up to the power-off instant is preserved. The recorder reboots and resumes; a power-loss event is logged in the audit trail. For absolute continuity, a small UPS or 24 VDC battery backup is the recommended add-on.

Flow totalizer working principle

The flow totalizer is composed of four parts: measurement loop, digital panel meter, regulator and power supply.

The stabilized power supply converts the 220V power supply into a stable DC voltage as the other part of the power supply.

The measurement loop processes the signal (voltage, current, etc.) sent by the flow transmitter into a voltage signal.

After A/D conversion, the signal is sent to a dedicated central processing unit for processing. Not only to the digital panel meter but also to the regulator. After comparing with the set value, it outputs a control or alarm signal according to the regulation rule.

The flow totalizer is used to measure the instantaneous flow of liquid or solid in the industrial field.

The signal output by the flowmeter is generally a pulse signal or a 4-20mA current signal, both of which output instantaneous flow. Our purpose is to calculate and display the instantaneous flow value and calculate the cumulative value in the PLC.

When the input signal is a pulse signal, when calculating the instantaneous flow rate, it must be calculated in strict time intervals to ensure the accuracy of the instantaneous flow rate.

Therefore, the calculation of instantaneous flow must be done with a timed interrupt. Moreover, only this one interrupt program can be run in the PLC system, and no other interrupts are allowed (even low-priority interrupts are not allowed to run). To prevent interference with the accuracy of the time interval of the timing interruption.

Calculating the instantaneous flow rate is to convert the number of accumulated pulses in this time period into the accumulated flow rate. Divided by time is the instantaneous flow.

For 4-20mA input, the instantaneous flow can be directly obtained by simply converting according to its corresponding range. The cumulative flow is to add up the cumulative flow in each time period.

In the actual use of PLC programming, the following issues must be paid attention to:

(1) Whether the input pulse frequency range exceeds the receiving range of the PLC;
(2) How to ensure correct calculation when the PLC high-speed counter reaches the maximum count value;
(3) How to ensure that the timing interruption is not disturbed;
(4) How to avoid errors in calculating the cumulative amount;
(5) The maximum cumulative digits of the cumulative amount;
(6) How to reset the totalizer.

Totalizer vs Flow Meter

A pure totalizer is not a flow meter.

Usually, flow meters measure instantaneous flow. If you need to know the total amount of flow, you need to use a totalizer.

A complete flow detection system includes several parts such as sensing, transmission, calculation, integration, display, etc. Each part can be an independent instrument. It is also possible to integrate several functions into one watch.

Many flow totalizers on the market now integrate calculation, totalization, and display. It includes most of the functions of the flow system. Some manufacturers set the totalizer and other parts as flow meters and use the name of the complete set on the totalizer. If you buy the totalizer alone, you will see that the name is flowmeter.

So the flowmeter [maybe] includes a totalizer, but the totalizer is not a flowmeter.

If you get here, you still can’t find a suitable product. Then let us take a more detailed look at the functions and applications of the Flow Totalizer Meter.

Paperless recorder working principle

A recorder is an instrument that converts the process of one or more variables over time or another variable into recognizable and readable signals. It can save the recorded signal changes for analysis and processing. The biggest feature of the recorder is that it can automatically record the slow change process and transient level change process of periodic or non-periodic multi-channel signals.

According to the types of input and output signals, recorders can be divided into analog-digital, digital-analog, analog-analog, digital-digital and other forms. Their main circuit varies according to the output form.

When the output is a digital signal, its main circuit is a memory circuit that can store digital information. It can send digital signals to tape drives, punchers or other equipment at any time. Or observe the analog waveform with an oscilloscope after proper conversion, such as digital memory and waveform memory.

When the output is an analog signal, the main circuit of the recorder is an analog amplifier drive circuit without storage function. The signal must be recorded on paper, photosensitive film, or tape immediately using appropriate recording devices and methods. The information can be saved for further analysis and processing. Such as various pen recorders, light recorders, plotters, tape recorders, etc.

What is a digital chart recorder?

Industrial digital chart recorders refers to an electronic instrument that remotely displays and counts signals such as pressure, temperature, flow, and liquid level in the industry.

Digital chart recorders record the collected data/calculated data in the internal storage system of the instrument with time as the base axis. It does not consume any commonly used recording facilities. For example: paper, pen and ink. Sino-Inst provides time-saving paperless chart recorders with up to 64 channels.

The stored data recorded in the instrument is displayed on the LCD screen after calculation and simulation. Commonly used LCD screens are widely used. On the LCD screen, digital display, bar graph display, curve display, alarm list, etc. can be displayed.

The data collected by the paperless recorder are commonly used: temperature, pressure, flow, liquid level, voltage, current, humidity, frequency, vibration, speed, etc.

Common Industrial Digital chart recorders:

Pressure recorder, flow recorder, speed recorder, temperature recorder, humidity recorder, liquid level recorder, level recorder, power recorder, F0 value recorder.
