Product Code : SCL-CELE-14022
This equipment is a self-contained water recirculating
unit designed to compare the performance of two primary flow measurement
devices: the Venturimeter and the Orifice Meter. They are
connected in parallel, allowing for the experimental study of each meter under
controlled flow conditions.
1. Key Components and Design
The apparatus uses two separate pipeline circuits originating
from a common manifold.
- Flow
Meters (Parallel Connection):
- Venturimeter: Made
of Clear Acrylic (transparent) and compatible with a 1 inch
Diameter Pipe.
- Orifice
Meter: Features an Orifice plate made of Stainless
Steel housed in a Clear Acrylic section, also compatible with
a 1 inch Diameter Pipe.
- Pressure
Measurement: Pressure tapings from both meters are
connected to a differential manometer (implied) to measure the
pressure difference (Delta P) across each device.
- Flow
Control: Valves are provided at the downstream of
each meter. This allows the operator to isolate one meter while the
other is operational.
2. Water Circulation and Flow Rate Measurement
A volumetric method is used as the high-accuracy reference
for calibration.
- Water
Circulation: Provided by an FHP Pump (Crompton make)
from the Sump Tank (50 Liters capacity).
- Flow
Rate Measurement (Actual Flow): Used to verify the meter readings.
- Achieved
using a Measuring Tank with a Piezometer (25 Liters
capacity).
- An Electronic
Stop Watch is provided to measure the time taken to collect a known
volume, calculating the actual discharge (Q actual).
3. Purpose and Experiments
The primary goal is the comparative analysis and calibration
of the two devices.
- Calibration:
Determine the Coefficient of Discharge (Cd) for both the
Venturimeter and the Orifice Meter at various flow rates.
- Performance
Comparison: Directly compare the operational
characteristics, particularly the permanent head loss, of the two
meters.
