Discharge Over Notches With Data Logging Facility manufacturer in india

MODAL NO: MTFM-103/DL

QTY


The setup consists of a channel having sufficient length and width in which water is supplied from the bottom. Set of three notches, i.e. rectangular notch, 60° V notch & 45° V notch is provided along with the set-up. Required Notch is fitted at one end of this channel. A level sensor is fitted to measure the height of fluid in flow channel. Any one of the notch can easily be attached and detached at the outlet of this channel without need of any extra tool. The flow channel is also fitted with calming section and flow smoothening plates to achieve undisturbed flow.

The flow channel is also fitted with calming section and flow smoothening plates to achieve undisturbed flow. Present set-up is self-contained water re-circulating unit, provided with a sump tank, centrifugal pump etc. Water is pumped by means of centrifugal pump and passing through the flow channel, it returns back to the sump which make the system re-circulating type. Flow control valve and by-pass valve are fitted in water line to conduct the experiment on different flow rates. Flow rate of water is measured with the help of flow sensor, fitted in water line. The supplied set-up is complete in all respect. Only water supply and electricity supply is to be provided by the end user for running the set-up. The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Lab view of National Instruments, USA. This software is compatible to interfacing unit designed by  Engineers. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computerizing software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.

•Tanks and Channel will be made of Stainless Steel.

•An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.

•The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.
