10. Level & Flow Measurement

Level Indicator, Controls, Sensors & Switches

Level Sensors provide vital information to process engineers and plant controls as to the level of bulk solids at any given stage of production. This information is then used to either reorder the material, refill the material or to take the next process decision. Depending on the process conditions and characteristics of the bulk solids, we provide suitable level sensors.

Commonly used level sensors are paddle type, capacitance type and tuning fork type. Other types of sensors available are diaphragm type, Tilt Switch etc..

Flow Sensors

In some gravity or pneumatic conveying applications, it is very critical to measure the flow rate of bulk solids. Mass flow sensors are used in such applications. Enge Plas provide solutions for critical bulk solid processes to detect conditions.

Enge Plas provide a wide range of solutions for flow measurement sensors in pneumatic conveying & free falling processes. Our mass flow measurement sensor is designed with the latest microwave technology for the flow of powders & solids that are conveyed in metallic pipes.

Moisture Sensors

Our in-line moisture measurement sensor ensures product quality by measuring the moisture inside the material core. moisture measurements are designed to allow for automation of drying or moisturising at different points in flow processes to minimise energy cost and maximise your profits.

The moisture sensor circuitry principle is centered around an electrical high frequency field that is based on developed and proven technology for several years.

Aeration Pads

The aeration pad is an aeration device used to promote the flow of dry bulk powders from a storage vessel. It operates by continuously introducing air into the body of the dry powder.

When a powder is first conveyed into a storage vessel it is actually a highly aerated mixture of air and particulate. In this state the mixture flows quite readily. However, as the powder settles the solid particulate and air separate resulting in a decrease in volume and an increase in bulk density. In this deaerated state powders can behave more like a single large solid structure rather than a fluid-like mixture. By replacing the naturally lost air, the air to particulate mixture ratio is held thus maintaining the fluid like characteristic of the aerated powder.

Pressure & Temperature Sensors

Pressure transducers operate on the proven principle of strain gauge technology. The pressure is transferred from the measuring diaphragm (which is flushed with the melt channel) via a capillary system to a second diaphragm. The capillary system is filled either with mercury or with a mercury-free medium. The second diaphragm is fitted with a strain gauge. Using the linear change in resistance in relation to deflection, an electric output signal is provided. The special membrane technology guarantees a very long operating life, even under the toughest conditions. The anti-adhesion coating reduces the risk of damage caused by frozen plastic melts.

Our range of temperature sensors features proven thermocouple or resistance temperature measurement systems in a high precision but robust sensor. The Fe-CuNi (type J or L) thermocouples which generate a voltage when heated are well established in the industry due to their advantages thanks to the high Seebeck coefficient. For such applications, type K thermocouples are also available (NiCr-Ni). Additionally, our PT100 (2, 3 or 4-wire) resistance temperature sensors have resistance of 100 Ohm at 0°C which changes with increasing temperature. Conforms to EUROMAP 31.
