Azbil JTD720A Smart Multivariable Flow Transmitter

Manufacturer: Azbil Corporation
Model: JTD720A

Feature

This transmitter simultaneously measures differential pressure, pressure, and temperature. Specifically, it uses these values to compensate for density changes. These fluctuations usually occur due to static pressure or temperature shifts. Consequently, the device outputs the mass flow rate or standard volumetric flow rate accurately.
The integrated compensation function allows for gas mass flow measurement with just one transmitter. Furthermore, the unit delivers high accuracy alongside exceptional rangeability. Users can also view real-time temperature and pressure values directly on the display. Therefore, this multivariable design simplifies installation and reduces the need for extra sensors.

Summary

The Smart Multivariable Flow Transmitter measures gas mass flow with extreme precision. It combines differential pressure, static pressure, and temperature sensors into one compact unit. This device compensates for density changes automatically to ensure data accuracy. It outputs a stable 4–20 mA signal for your control system. You get reliable mass flow readings despite constant process fluctuations.
This single device replaces multiple transmitters and separate computing units. Consolidating functions lowers your total purchase and wiring costs significantly. It also simplifies maintenance and reduces your spare parts inventory. Fewer devices in the loop minimize potential measurement errors. You achieve much higher system accuracy through this integrated design.
The transmitter fits into your current piping without any physical modifications. It works perfectly with existing orifices and connection pipes. You simply replace the old unit and update the software settings. This allows a fast switch to mass flow monitoring. You save significant time by reusing your current infrastructure.
Advanced dual sensors provide a wide 135:1 rangeability for diverse applications. The unit maintains  ±0.1% FS accuracy for pressures above 5 kPa. This ensures reliable data at both high and low flow rates. Consequently, you can trust these measurements across various industrial conditions.
An optional digital indicator shows flow, temperature, and pressure simultaneously. This eliminates the need for extra mechanical gauges at the site. Therefore, operators check all vital data at the installation point easily. This feature improves safety and simplifies daily site inspections.
The device offers dedicated density compensation for saturated steam lines. It calculates density using only static pressure data accurately. This removes the requirement for additional temperature sensors in steam applications. Finally, you gain strict control over utility steam usage and energy costs.
