Page 11: Chapter 2 Introduction
Introduction Introduction Topics covered in this chapter: • System description • Product recycling/disposal System description The 8700M Magnetic Flowmeter Platform consists of a sensor and a transmitter. The sensor is installed in-line with the process piping; the transmitter can be integrally mounted or remotely mounted to the sensor.
Page 12 Introduction Figure 2-3: 8705 flanged sensor Figure 2-4: 8711 wafer sensor Figure 2-5: 8721 hygienic sensor The flow sensor contains two magnetic coils located on opposite sides of the sensor. Two electrodes, located perpendicular to the coils and opposite each other, make contact with the liquid.

Page 16: Location And Position
Sensor Installation Location and Position 3.2.1 Environmental considerations To ensure maximum transmitter life, avoid extreme temperatures and excessive vibration. Typical problem areas include the following: • High-vibration lines with integrally mounted transmitters • Tropical/desert installations in direct sunlight • Outdoor installations in arctic climates Remote mounted transmitters may be installed in the control room to protect the electronics from the harsh environment and to provide easy access for configuration or service.
Page 17 Sensor Installation Figure 3-2: Flow direction arrow 3.2.4 Sensor piping location and orientation The sensor should be installed in a location that ensures it remains full during operation. Depending on where it is installed, orientation must also be considered. • Vertical installation with upward process fluid flow keeps the cross-sectional area full, regardless of flow rate.
Page 18: Sensor Installation
Sensor Installation 3.2.5 Electrode orientation The electrodes in the sensor are properly oriented when the two measurement electrodes are in the 3 and 9 o’clock positions or within 45 degrees from the horizontal, as shown on the left side of Figure 3-4.
Page 19 Sensor Installation Note Metallic or spiral-wound gaskets should not be used as they will damage the liner face of the sensor. If spiral wound or metallic gaskets are required for the application, lining protectors must be used. Figure 3-5: Gasket placement for flanged sensors Grounding ring and gasket (optional) Customer-supplied gasket Bolts...
Page 20 Sensor Installation If leakage occurs at the suggested torque values, the bolts can be tightened in additional 10% increments until the joint stops leaking, or until the measured torque value reaches the maximum torque value of the bolts. Practical consideration for the integrity of the liner often leads to distinct torque values to stop leakage due to the unique combinations of flanges, bolts, gaskets, and sensor liner material.

Digital Signal Processing 10.4 High process noise diagnostic The transmitter continuously monitors signal amplitudes over a wide range of frequencies. For the high process noise diagnostic, the transmitter specifically looks at the signal amplitude at frequencies of 2.5 Hz, 7.5 Hz, 32.5 Hz, and 42.5 Hz. The transmitter uses the values from 2.5 and 7.5 Hz and calculates an average noise level.

When using 37 Hz coil drive mode it is important to zero the system for the specific application and installation.
Page 143 Digital Signal Processing The operating mode should be used only when the signal is noisy and gives an unstable output. Filter mode automatically uses 37 Hz coil drive mode and activates signal processing at the factory set default values. When using filter mode, perform an auto zero with no flow and a full sensor.

Maintenance The flow rate reading after warm-up should be between 29.97 (9.1 m/s) and 30.03 ft/s (9.2 m/s). If the reading is within the range, return the transmitter to the original configuration parameters. If the reading is not within this range, initiate a digital trim with the LOI or Handheld Communicator.

Page 224: Universal Capability
Implementing a Universal Transmitter Universal capability The transmitter has the ability to drive other manufacturers' sensors. In addition to providing a flow measurement, all diagnostic functionality is available. This capability can provide additional information about the installation, the process, and the health of the sensor.
Page 225: Wiring The Universal Transmitter
Implementing a Universal Transmitter Method 2: Involves the conversion of the existing sensor calibration number / meter factors to an equivalent Rosemount 16-digit calibration number. Accuracy of the meter using this methodology is estimated to be in the range of 2-3%. Contact the Rosemount technical support for more information on this method or to determine a calibration number for the existing sensor.
