Dwyer Instruments IEF-SB-PG-LCD | Insertion Electromagnetic flow transmitter | Standard accuracy 4-36" (100-900 mm) pipe | 1% FS | 1" male BSPT | pg gland without cable with LCD display
The Model IEF-SB-PG-LCD Insertion Electromagnetic Flow Transmitter is an adjustable insertion flowmeter using electromagnetic technology that provides many continuous signal outputs along with an accurate and dependable measurement of fluid velocity. This series is particularly made to provide excellent performance together with ease of use and installation. One device has many output possibilities, including configurable BACnet MS/TP or Modbus® RTU communications protocol over 2-wire RS-485 in addition to the typical analog, frequency, and alarm outputs. It can accommodate pipe widths ranging from 4" to 36" (102 to 914 mm).

- Field configurable setup displays (-LCD integral option or remote accessory A-IEF-DSP) can be used to meet application requirements because they can accommodate multiple display configurations (such as alarm outputs, communication outputs, pipe size, pipe material, liquid type, analog output, pulse/frequency output, damping, and calibration factor) with a single model.
- As temperature, density, or viscosity varies, maintain system efficiency with great performance precision.
- With an installation tool and setup wizard that are straightforward to use and enable exact installation, ordering and setup are quick and simple.
- With the accompanying thickness gage and measuring tape, accessory setup kit A-IEF-KIT assures precise installation application depth, saving you time.
- Long product life, lower costs, and less maintenance needed since there are no moving components to wear out or break and fouling-inhibiting electrodes.
- Reduce installation costs with isolation valve accessory choices that enable hot-tap kit installation in running systems or simple removal without requiring system downtime.
- The NIST traceable pass/fail verification certificate for Carbon Steel Schedule 40 pipes in the sizes of 4" (102 mm), 6" (150 mm), and 8" (200 mm) must be accompanied by the necessary paperwork.
