Electromagnetic Flow Meter shall be a velocity sensing Electromagnetic type micro processor based signal converter, sealed housing, flanged tube meter for 1.0 Mpa working pressure, manufactured to highest standard available for mag-meters, equipped with minimum six digit digital totalizers, reading in units of (kilolitres/ cubicmeter) and shall be accurate within 0.5% of Measured value, shall operate within a range of 0.3m/sec to 4 m/sec and be constructed as follows:Meter tube (Sensor) shall be fabricated from stainless steel tube and use class PN10 flat face carbon steel flanges in accordance with IS 1538. These flanges shall be welded to the flow tube. The internal and external of the meter tube shall be blasted to near white and lined with hard rubber/ Polyurethrene/ PTFE preferably by SBR or EPDM. Meter tube shall have a constant nominal inside diameter offering no obstruction to the flow. The accuracy should be inclusive of linearity, hysteresis, repeatability, temperature and pressure effects Coil Housing shall be fabricated from stainless steel (SS 304) with Anticorrosive paint for corrosion resistance and welded to the tube providing a completely sealed environment for all coils, electrode connections and wiring harness capable of submerged or buried operation with IP 68 protection. Signal Converter shall be pulsed DC coil excitation type with auto zeroing. The signal converter shall be remotely mounted away from the meter. The converter shall indicate direction of flow and provide a flow rate indication and a total of flow volume for both forward and reverse directions.The converter shall provide an isolated 4-20 mA output into minimum 500-ohm load and a frequency output of a maximum of 0-10 KHZ and a scaled pulse output, Communication interface is RS485, HART output, . The microprocessor based signal converter shall have a self-diagnostic test mode and a backlit display that continuously displays “Rate of Flow” and “Total Volume”. Converter shall be supplied with a programmable low flow drop out Higher flow and empty pipe zero return. The signal converter housing should be die-cast aluminium with glass window. The converter cum transmitter should be fully programmable form the front facia. The programming should be user friendly, self-prompting menu driven. Flowmeter test calibration certificate from FCRI, flow test lab/ NABL accredited lab to be furnished.
