Description

Purpose of the stand: the stand is designed to study instruments for measuring pressure, flow and temperature of water in water supply systems. Measurements are carried out in automated and manual experiment modes. For the automated mode, the stand includes a laptop with an ADC board.
The stand is a hydraulic system that allows you to measure fluid flow, pressure and temperature using various devices. It consists of a liquid supply system, a liquid heating system, and a system for measuring the amount of liquid supplied.
The devices and instruments under study are installed on the stand in such a way that it is possible to compare the readings of different types of measuring instruments when measuring the same parameter.
The devices and instruments under study are manometers and pressure sensors of various types, flow meters and quantity counters, temperature sensors and thermometers.
List of laboratory works:
1. Instruments for measuring temperature.
2. Dynamic characteristics of the thermistor converter (manual measurement mode).
3. Dynamic characteristics of the thermistor converter (automatic measurement mode).
4. Pressure measuring instruments. Pointer deformation pressure gauge.
5. Pressure measuring instruments. Pressure sensor of deformation membrane type.
6. Study of the volumetric method of measuring water flow.
7. Studying the method of measuring water consumption using the readings of a water quantity meter.
8. Study of a method for measuring water flow by the pressure drop across a measuring diaphragm.
9. Reading the pump characteristics.
The stand includes: – a frame structure in the form of a table on wheels with a pull-out table for placing a laptop; – a water tank mounted under the tabletop; – dashboard; — Pressure Sensors; – temperature sensors; — water meter; – measuring diaphragms; – pressure gauges; – pump for supplying water to devices for measuring flow, pressure and temperature.
The stand is supplied with a laptop with software for performing laboratory work.
