Bids Are Invited For Acquisition Of Ultrasonic Flow Meters For Saae Use In Pimenta/Mg.

Ultrasonic Flow Meter For Continuous Flow Measurement Of Effluent In The Ete, With The Following Minimum Characteristics: Ultrasonic Measurement Without Contact With The Liquid; Includes Ip67 Protection Class Ultrasonic Sensor And Ip65 Protection Class Remote Controller With Black Light Lcd Display; Measuring By Level Or Distance; With Two Alarms For High Level And Two Alarms For Low Level; Analog Signal Output 4 A 20 Ma And Communication Output Rs 485Modbus Rtu; Measuring Range With Sensor For 50 Mts; Temperature -20°C To +50°C. Explanatory Note: Ultrasonic Sensor (Based On The Emission Of Ultrasound Pulses Emitted By The Sensor, Which Will Be Reflected By The Element (Liquid Or Solid) To Be Emitted, And Detected Again By The Sensor. Thus , Level Measurement Occurs Without Any Kind Of Physical Contact Between The Instrument And The Measured Medium, Where The Distance Between The Sensor And The Level Is Identified As A Function Of The Time That The Ultrasonic Pulse Takes To Travel The Space Between The Sensor And The Existing Level In The Reservoir).Note Explanatory: Remote Controller (Allows The Viewing Of Application Data At A Distance From The Ultrasonic Sensor That Must Be Installed In The Tank Or Reservoir, Keeping The Controller Module At A Suitable Point For Viewing The Measurement, Implementing Parameterization And Connection Electric For Power Supply And Automation Signals)., Ultrasonic Level Sensor – Remote: Level Measurement, Ultrasonic Remote Level Transmitter, For Use In The Eee – Sewage Pumping Station; Integral Communication Cable Should Be 20 Meters; The Transducer Material Must Be Resistant To Extreme Environments Such As Acids, Alkalis, Salts, Corrosion And High Temperatures; It Must Have The Ability To Connect To Several Display Systems, A Minimum Of Two Pumps For Management; The Meter Must Not Have Direct Contact With Liquid; Possess A Cable Press; Possess An Identification Plate In Stainless Steel; Have An Internal Surge Protection Device; Have The Following Minimum Specifications: Measuring Range: 0 ~ 25M; Blind Area: 0.25M~0.8M; Measurement Accuracy: 0.25%; Resolution: 1.0 Millimeter; Analog Output: 4 ~ 20 Ma Relay Output: 2; Supply Voltage: Dc24vdc / Ac220v, Lightning Proof; Ambient Temperature: -20℃~+60℃; Enclosure Protection: Ip67; Non-Contact Pendulum Mounting Or Similar Structure; Lcd Display With Instantaneous Level Indication; Mounting: Remote And Local; Input Cable: 1Npt; Maximum Impedance Of 750W; Electronic Circuit: Microprocessed.
