Tools for the meter technician – do you see anything missing?

If one is to do his work well, he must first sharpen his tools. In their work, instrument maintenance personnel not only need to improve their technical skills but also need to have a set of practical tools for repairs. So, what kinds of small tools are used during instrument maintenance? Instrument Workshop Tool List – Essential Instruments 1. Temperature instruments: The chemical reactions and processes that take place in petrochemical production can only proceed smoothly under specific temperature and pressure conditions. To monitor temperature changes in real time and maintain precise control over the temperature range, a certain number of temperature instruments must be installed in the production process. Currently, contact measurement is primarily used for determining the production temperature; temperature data is obtained using temperature-sensing elements such as thermocouples and thermal resistors, and field bus technology is employed to achieve automated temperature control. 2. Pressure instruments: There are a variety of types of pressure instruments, such as pressure sensors, pressure transmitters, and special-purpose pressure gauges. These instruments can be used for measuring pressure in extreme environments with high temperatures or corrosive conditions, as well as in situations involving crystalline or granular media. 3. Depending on the measurement method, level gauges can be classified into buoyancy type, direct-reading type, differential pressure type, radiation type, radar type, etc. In petrochemical production, radar level gauges are increasingly favored by the industry due to their high measurement accuracy and strong suitability for petrochemical materials. 4. Flow meters Flow meters are based on two main measurement principles: one is volume flow measurement, and the other is mass flow measurement. Orifice plate differential pressure flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, vortex flowmeters – almost all flowmeters available today are those that measure volumetric flow rate. Since intelligence is being used nowadays, the mass flow rate can be measured simply by adjusting the internal parameters of the flow meter.
