6.2. 5. Level Transmitters Level measurement techniques are vital and crucial part of the process instrumentation market. There are several technologies for sensing and measuring level. The different technologies which are used in the working of the level transmitters are: magnetostrictive, vibratory probes, hydrostatic , magnetic and mechanical floats, pneumatic , capacitance, radar and ultrasonic etc. SAMPLE TABLE 2: LEVEL TRANSMITTERS MARKET REVENUE, 2012 – 2018 ($BN) Type 2012 2013 2014 2015 2016 2017 Magnetostrictive Vibratory Probe Hydrostatic Magnetic & Mechanical Float Pneumatic Others Total XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX 3.3 XX XX 3.57 XX XX 3.78 XX XX 4.01 XX XX 4.25 XX XX 4.53 2018 CAGR% (20132018) XX XX XX XX XX XX XX XX XX XX 4.89 XX XX 6.49% Source: IndustryARC Analysis, Expert Interviews, Annual Reports The table above shows the different types of level sensors based on their underlying technology. The global market is expected to increase from around $3.57bn in2013 to around $4.89bn by 2018, growing at a CAGR of around 6.49%. Level sensing technologies are categorized into two types: Contact and Non-Contact based on the nature of level sensing – mechanical or electronic, respectively. Contact Level sensors are the level sensors using traditional technologies such as magnetostrictive, vibratory probe, hydrostatic, magnetic & mechanical float, pneumatic & so on which are mechanical in nature. Contact level sensors have had widespread penetration across several industry verticals by being deployed in several products over the years. However, they are slowly being replaced by non contact level sensors since the past few years, as the latter are more accurate, sophisticated sensors using technologies such as capacitive, conductivity, ultrasonic & so on, which are electronic in nature. The others market contains emerging technology types like ultrasonic, capacitive, radar etc. An ultrasonic level sensor emits high frequency acoustic signals which are reflected back and sensed IndustryARC | 16
