Description:

The Rosemount 8750W magnetic flowmeter brings together performance, reliability and intelligent diagnostics to create a superior solution for water, wastewater and utility flow measurement.

Available in sizes ranging from 1/2 inch to 48 inches, the 8750W features fully welded construction to withstand vibration and dual-compartment transmitter housing to keep electronics isolated from moisture and contamination. This robust design provides the reliability and accuracy needed to keep important processes running.

The 8750 includes a field or wall mounted transmitter for fast, intuitive, and easy configuration. The field mount Rosemount 32ES transmitter includes die cast aluminum housing for excellent reliability. It is available with an optional backlit two line by 16 character local operator interface, and the transmitter can be configured by optical switches to simplify adjustments without removing the cover.

The wall mount Rosemount 12ES transmitter features an easy to use operator interface and the Rosemount magmeter diagnostics. The intuitive 15 button keypad provides instant access to the most commonly used functions, and the 2 line by 20 character display provide clear indication.

The Rosemount 8750W uses wafer or flanged process connections. Flanged sensors are fabricated from stainless and carbon steel and welded to provide a hermetic seal that protects against moisture and other contaminants.

The flangeless design of the wafer sensor makes it an economical, compact, and lightweight alternative to flanged models. Alignment spacers provided with every sensor assist with centering the sensor in the process line making installation easier.

Applications:

The Rosemount 8750W magnetic flowmeter brings together performance, reliability and intelligent diagnostics to create a superior solution for water, wastewater and utility flow measurement.

Specifications:

Functional specifications
Service
Water and water-based fluids
Line sizes
1 /2 -in. to 48-in. (15 mm to 1200 mm)
Sensor compensation
Rosemount sensors are flow-calibrated and assigned a
calibration factor at the factory. The calibration factor is entered
into the transmitter, enabling interchangeability of sensors
without calculations or a compromise in accuracy.
Conductivity limits
Process liquid must have a conductivity of 5 microsiemens/cm
(5 micro-mhos/cm) or greater.

Pressure limits
Per ASME B16.5 and ASME B16.47 for the flange selected.
Sensor coil resistance
flanged: 7 - 16
wafer: 10 - 18
Flow rate range
Capable of processing signals from fluids that are traveling
between 0.04 and 30 ft/s (0.01 to 10 m/s) for both forward and
reverse flow in all sensor sizes. Full scale continuously adjustable
between –30 and 30 ft/s (–10 to 10 m/s).
Sensor ambient temperature limits
–20 to 140 °F (–29 to 60 °C)
Process temperature limits
Polyurethane lining
0 to 140 °F (-18 to 60 °C)
Neoprene lining
0 to 185 °F (-18 to 85 °C)
PTFE lining
-20 to 248 °F (-29 to 120 °C)
