Level & Pressure Transmitter for Chemical Injection System

Date: 2022-Jan-29

As an indispensable and important energy source for modern industrial society, oil extraction methods are continuously optimized along with technological progress. In the process of oil extraction, chemical treatment plays a key role in optimizing performance, reducing costs, and extending the life of oil and gas industrial facilities, infrastructure, and reservoirs. Correct chemical injection is critical to successfully reducing chemical and microbiological reactions, process and flow assurance issues, and improving production and operational efficiency.

The flow monitoring of chemical injection and the remote monitoring of the liquid level of the storage tank provide practical solutions for the realization of digital oil fields. In terms of level monitoring of chemical storage tanks, Micro Sensor provides reliable corrosion-resistant pressure sensors with analog and digital outputs, and highly stable pressure sensors to ensure the continuous accurate level monitoring data and help the chemical injection system to quickly adjust its chemistry product dosage, reduce labor costs.

 Chemical Storage Tank Level Monitoring

However, the current level monitoring of chemical storage tanks still has the following challenges:

Temperature Changes

Almost all sensors are susceptible to environmental temperature fluctuations, these fluctuations will affect the measured fluid, measuring process, or the sensing element itself, so the sensor itself needs to be temperature compensated.

Inclined/Inclined Water Tanks

When storage tanks are installed on the well site, they are rarely located on flat concrete pads. Instead, they sit on metal legs on uneven ground. This will cause the fuel tank to tilt to one side, making it difficult to know the real level.


Chemicals that foam on the surface may cause difficulties in the measurement of the device.


The accumulation of condensation on the equipment affects the accuracy of the sensor.

Chemical Compatibility

The sensor in direct contact with the medium needs to be made of a material compatible with the measured medium.

Based on the several difficulties in chemical storage tank level monitoring, Micro Sensor provides products with different measurement principles such as LR725 ultrasonic level gauge, MPM489 pressure transmitter and M20 pressure transmitter to deal with different working conditions on site, therefore the data can be accurately monitored.
