The world’s seawater quality is becoming increasingly alarming because many seawater parameters are changing over time. Seawater pH, for instance, has been increasing since the indistrial revolution 200 years ago. This happened because seawater absorbs 25% of all man-made carbon emissions. So for every 4 cars on the road, your seawater is absorbing carbon emission from one of them. According to experts, seawater acidity may increase 150% by end of the century if nothing is done to reduce global carbon emission.
Global warming is also increasing seawater temperature. The seawater temperature increase from 1980 to 2023 has been aroun 0.6 C. This increase is lethal for aquaculture species because shrimp/fish diseases thrive in warm water. There is also strong correlation between seawater temperature, DO (dissolved oxygen), pH, salinity, TDS, photosynthesis, compound toxicity, CO2, etc. Hence, increase in seawarer temperature will increase/reduce seawater DO, pH salinity, TDS, photosynthesis, compound toxicity, CO2, etc. These changes is stressful to shrimp/fish, making them more vulnerable to diseases and death.
Sudden weather change also affects seawater quality in shrimp/ponds. Acid rain, for instances, causes change to seawater salinity, temperature and acidity. When any of these changes are ecxessive, shrimp/fish becomes more vulnerable to stress, diseases and death.
The key to avoiding all the above is continuous monitoring of seawater conditions so that immediate actions can be taken whenever seawater conditions become unsafe or critical to shrimp/fish. But this cannot be done manually by human becayse this is too time and energy consuming. So a better an smarter monitoring solution is needed to better equip the shrimp/fish farming communities.
LIQUISENS Smart Water Monitoring Solution

LIQUISENS is a smart water monitoring solution that continuously measures temperature, pH ORP (dissolved oxygen or DO), and conductivity (salinity). Unlike other seawater measuring equipment, LIQUISENS uses only 1 probe to measure all 4 seawater paramters. Hence, LIQUISENS is more user-friendly and time efficient. LIQUISENS can also be set to measure these four seawater parameters per 5 minutes or longer, based on you desires prefences.
All data collected by LIQUISENS are stored directly in cloud for users to access via mobile phones and tablets. This reduces the need for users to manually write data on books, etc. To (incrase efficiency), all the collected data are presented in graph form so that users can quickly interpet and conclude conditions of shrimp/fish pond within minutes.
But best of all, users can receive REAL-TIME notification whenever seawater condition(s) is at unsafe or critical level for shrimps/fish. If necessary, notifications can be sent via WhatssApp to more than one user so that more people can be assigned to take immediate actions to remedy seawater conditions.
With LIQUISENS, shrimp/fish farming companies and bussiness owners can now take preventive actions before seawater conditions worsen to cause shrimp/fish fatalities. This is the key to reducing mortality rates and preventing shrimp/fish harvesting failure. This is the solution everyone in the aquaculture sector is waiting for!
Advantages of LIQUISENS Smart Water Monitoring System
- Convenient; measures 4 different seawater parameters at same time with only 1 probe.
- Smart; warning notification is sent immediately whenever any of the 4 seawater parameters is at unsafe or critical level for shrimps/fish.
- Efficient; can monitors up to 4 ponds at same time because 4 probes can be connected to each system.
- Powerful; data are presented in graph forms so that users can better interpret pattern and actual conditions of ponds.
- Low cost; equipped with solar panel and rechargeable battery. Battery can last for days after fully charge.
- Low maintenance; calibration are done remotely so that users don’t have to waste time and resources to make any probe adjustment.
- Accurate; seawater measurement is done at bottom pond and always at same depth becaude probe is done at bottom pond and always at same depth because probe is connected to floating buoy.
- Durable; made in Belgium and comes with 2 years warranty
