ONICON’s FT-3500 series is a versatile insertion electromagnetic flow meter and thermal energy measurement system. Designed to measure electrically conductive liquids in a variety of applications, the FT-3500 features a remote touch screen display that allows users to interact intuitively with measurement values, application details, and configuration settings. The advanced FT-3500 transmitter features a native BACnet and MODBUS communication protocol via IP or RS485, as well as a dual analog output for flow or energy rate.

Additionally, the FT-3500 boasts a high-resolution frequency and three scalable pulse outputs for totalization or alarm signals. It is available for use in pipes ranging in size from 1¼" to 72" in diameter.

The FT-3500 Insertion Electromagnetic Flow Meter features ONICON's unique hot tap design that allows for easy insertion or removal from the pipe without the use of special tools and without disrupting flow. The low maintenance design is provided ready-to-use without the need for field programming.

FT-3500 Insertion Electromagnetic Flow Meter Typical Applications

The FT-3500 is ideal for chilled water, hot water, domestic water, condenser water, water/glycol, and municipal water applications.

Highly Accurate Over a Wide Flow Range

Highly efficient sensor design and continuous auto-zero function improve accuracy and sensitivity, particularly at low flow rates. Each flow meter is individually wet calibrated and accurate to within ±1% of reading.

Simple Installation and Commissioning

Each FT-3500 is factory configured and ready for use upon delivery.

Excellent Long Term Reliability

Low maintenance, no-moving-parts flow sensing technology works well in difficult flow measurement applications such as open loop condenser water flow.

Ideal Solution for Retrofits

The innovative hot tap adapter design allows for wet tapping pipes without interrupting flow.

Touch Screen Remote Display

All process data and programming functions are accessible via user friendly display.

BTU (Energy) Meter Option

When ordered with the thermal energy (BTU) meter option, the FT-3500 becomes a complete thermal energy measurement system providing accurate flow, energy, and temperature data.
