Product Code : SCL-CELE-14014
This equipment is a self-contained water recirculating
unit designed for the experimental study and calibration of the Bend
Meter. This device measures flow rate by sensing the differential
pressure created across a standard pipe bend due to the effect of
centrifugal force on the flowing water.
1. Key Components and Design
The apparatus is built around a standard pipe bend used as
the primary flow sensor.
- Bend
Meter: The flow-sensing element is a pipe bend.
- Material: Stainless
Steel.
- Compatibility:
Compatible with a 1 inch Diameter Pipe.
- Principle: Pressure
tapings are taken from the inner and outer curves of the bend to a differential
manometer (implied) to measure the pressure difference ($\Delta P$).
- Flow
Control: A Flow control valve and a by-pass valve
are fitted in the water line to accurately regulate the flow rate,
allowing the experiment to be conducted at different flow rates.
2. Water Circulation and Flow Rate Measurement
A volumetric method is used as the high-accuracy reference
for flow rate.
- Water
Circulation: Provided by an FHP Pump (Crompton make).
- Sump
Tank: 50 Liters (approx.) capacity. All tanks are
made of Stainless Steel.
- Flow
Rate Measurement (Actual Flow): This serves as the true flow
reference for calibration.
- Achieved
using a Measuring Tank (25 Liters (approx.) capacity).
- An Electronic
Stop Watch is used to measure the time required to collect a known
volume, calculating the actual discharge (Q actual).
- Structure
& Control: The set-up includes a Control Panel with
standard On/Off Switch and Mains Indicator.
3. Purpose and Experiments
The primary goal is the calibration and demonstration of the
bend meter's operational principle.
- Calibration:
Determine the Coefficient of Discharge (Cd) for the bend meter by comparing
the actual flow rate (measured volumetrically) with the theoretical
flow rate (calculated from the differential pressure reading).
- Principle
Verification: Demonstrate how centrifugal force on the
moving fluid creates a pressure gradient (differential pressure) across
the bend, and that this gradient is proportional to the flow velocity
squared.
