FPI MagTM Model 395L Suggested Specifications General The magmeter shall consist of two components; an electromagnetic averaging sensor and a converter unit. The magmeter shall automatically sense and correct for shifting velocity profiles in the pipe by constantly obtaining an area weighted mean velocity. The meter shall be equivalent to the Model 395L Full Profile Insertion Electromagnetic Averaging Mag Meter as manufactured by McCrometer, Inc. in Hemet, California. Converter The flowmeter converter shall be microprocessor based with a keypad for instrument set up and LCD displays for totalized flow, flow rate engineering units and velocity or totalized flow. The converter shall power the flow-sensing element and provide a galvanically isolated 4-20mA output for flow, and a flow proportional output. It shall be possible, in the test mode; to easily set the converter outputs to any desired value within their range. The 4-20mA scaling, time constants, pipe size, flow proportional output, engineering units and test mode values shall be easily set via the keypad and display. Two separate fully programmable alarm outputs shall be provided to indicate high/low flow rates, empty pipe, fault conditions, reverse flow and over-range conditions. The converter shall periodically perform self-diagnostics and display any resulting error messages. All set up data and totalizer values may be protected by a password. Sensor The flow-sensing element shall be of an electromagnetic multi point averaging type design and factory calibrated to traceable standards, such as NIST. Single point insertion or pressure port sensors shall not be acceptable. Installation of the averaging sensor shall be accomplished under flowing conditions through a 2-inch tap via a full port ball valve or corporation stop into the pipe. Profiling or site calibration shall not be required. Measuring electrodes and reference ground electrodes shall be constructed of 316 stainless steel to ensure no corrosion occurs by the passing fluid. Sensor shall have an epoxy coating over stainless steel to help from attack of UV, chemical resistance and excess buildup. Sensor shall be suitable for clean, potable, raw (check algae content) or other debris-free water applications. The sensor shall not be damaged by extended operation at partially full or empty pipe conditions. Sensor Cable The sensor cable is 20 feet of multi-conductor; abrasive resistant, polyurethane jacketed cable flexible to -40°F. The sensor cable shall be permanently bonded to the sensor. Additional sensor cable, up to 250 feet shall be available as an option. Mounting Hardware Stainless steel retaining rods, of sufficient length, shall be provided for the smooth installation of the electromagnetic averaging sensor. Shorter stainless steel retaining rods shall also be provided for the continuous operation of the electromagnetic averaging sensor. In order to provide stable and secure sensor placement, the sensor shall be capable of compression up to 300 PSI for use in low pressure PVC pipes and 450 PSI for use in low pressure metal pipes. For applications other than low pressure, contact factory for compression instructions.
