Features:

1. Comparison  and  calibration  of  different flowmeters

2. Direct comparison of flow measurement of various flow meters

3. Used  for  comparing  and  showing  the accuracy, losses, and use of fundamental in fluid mechanics applications that become important in many process engineering systems. Different types of flow meters are used based on applications and processes. It becomes important to study the flow measurement using different types of flow meters and their calibration.

Tesca Flow Meter Measurements & Calibration Trainer consists of a Venturi meter, variable area meter, and an orifice flow meter and pitot tube, installed in a series configuration to permit direct comparison. A flow control valve permits variation of the flow rate through the circuit. Pressure tappings are incorporated so that the head loss characteristics of each flow meter may be measured. These tapings are connected to a four or eight- tube manometer bank incorporating a manifold with an air bleed valve. Pressurization of the manometers is facilitated by a hand pump. The circuit and manometer are attached to a support framework that stands on ‘Tesca Hydraulic Bench 32097’. The Hydraulic Bench is used as the source of water supply and for calibrating the volumetric flow of the meters.

Optionally, differential pressure sensors, electro-magnetic flow rate sensors also available
