Process instrumentation is designed to measure variable parameters like flow, level, pressure, moisture, humidity, etc. They help measure the variables in the process of manufacturing to maintain the quality of the end product so that the customers remain satisfied. Here are some of the most important instruments industries use to monitor the various parameters during the manufacturing process.
It is a device designed to keep track of the flow rate of a gas or liquid moving through a closed duct. The reason why it is so important to measure the flow of the liquid is that it helps to evaluate the specific proportions required for the production process. Also, the maintenance of definite flow rates is crucial for accurate product quality control and efficiency.
If the flow measurement is incorrect, even a small percentage of error can cost you large sums of wastage of time and money. Look for the manufacturers who deliver optimum flow metering solutions to the industries based on your application demand and budget.
Level measurement estimates the maximum and minimum level of solid or liquid in a tank or container. The two devices used to measure flow are:
A level switch is a sensor used in the factories to detect the presence of powder, granulated materials, or liquid at a specific location. Suppose a tank is supplied with liquid, and it overflows. To prevent this overflow, a level switch is installed near the top that outputs a signal when the liquid touches it. Also, when the liquid level drops, the level switch prevents the complete draining of the tank. This way, it helps keep the liquid from overflowing, as well as draining.
This device measures the volume of granulated materials, liquid or powder. Just like a level switch measures the level of fluid at a specific point, a level meter gives a reading of the total volume of the liquid in a tank. It can monitor and control the volume in more significant details as compared to a level switch.
Pressure measuring techniques are used to measure not only the differential pressure or process but also the level, volume, mass flow, and density in all the areas of process technology. In differential pressure measurement, pressures act on a fluid-filled, pressure difference measuring cell. A differential pressure transmitter measures the pressure of gases, liquids, and vapors in closed vessels, and converts the pressure differential into electronic signals. It gives a wide application spectrum- thanks to a variety of measuring ranges and process fittings.
Humidity is a quantity representing the number of water vapors present in the atmosphere. It is essential to measure the RH% or humidity as it may create problems in the drying process in the industries or the stability chambers in the laboratories. A humidity transmitter or a portable humidity instrument helps measure the relative, as well as absolute humidity in %.
Temperature is a measure of hot or cold in a specific location. In the manufacturing process, infrared/portable/contact temperature measurement helps to analyze the expected temperature of a liquid, material, or substance. Besides, some thermal imagers also help to inspect the building for any faults or leakages.
These are some of the many instruments used to measure and control the variables in an industry. Find a reliable manufacturer and browse from a wide range of process instrumentation to find the best ones that cater to your needs.
