The IMSTL series is a submersible level and temperature transmitter suitable for use in freshwater aquaculture environments. This robust device accurately measures both water level and temperature, providing crucial data for maintaining optimal conditions in fish farms, hatcheries, and other aquatic facilities.
The IMSTL utilizes hydrostatic pressure sensing technology to determine water level. This method involves measuring the pressure exerted by the water column above the sensor, which directly correlates to the depth. This is a highly reliable and accurate technique for level measurement in aquaculture applications, as it is unaffected by water turbidity or the presence of suspended solids. The temperature measurement is achieved using a precise platinum resistance thermometer (PRT). PRTs are known for their stability and accuracy, ensuring that the IMSTL delivers reliable temperature readings over its wide operating range.
A key advantage of the IMSTL is its dual output capability. It provides two separate 4-20mA current output signals, one for level and one for temperature. This allows for independent monitoring and control of these two critical parameters. The 4-20mA signal is a widely used standard in industrial instrumentation, ensuring compatibility with a broad range of monitoring and control systems. This makes it easy to integrate the IMSTL into existing aquaculture management systems or to use it as part of a new installation.
The IMSTL is designed to withstand the harsh conditions encountered in aquaculture environments. Its IP68 rating ensures complete protection against dust and prolonged immersion in water. The 316L stainless steel housing and Viton seals offer excellent resistance to corrosion and chemical attack, ensuring long-term reliability and performance. The transmitter is supplied with a durable PVC cable, available in various lengths to suit different installation requirements. The cable is terminated with a flying lead, allowing for flexible connection options.
The IMSTL is suitable for a wide range of aquaculture applications. It can be used in fish ponds, tanks, raceways, and other freshwater systems. Typical use cases include:
- Monitoring water levels in fish ponds: Ensuring optimal water depth for different fish species.
- Controlling water circulation and aeration systems: Maintaining appropriate oxygen levels and water quality.
- Monitoring temperature in breeding tanks: Providing ideal conditions for fish spawning and larval development.
- Controlling heating and cooling systems: Regulating water temperature to optimize fish growth and health.
The IMSTL‘s compact size and G1/4 male DIN3852 process connection with a removable nose cone allow for easy installation in various locations within the aquaculture system. The removable nose cone facilitates cleaning and maintenance, ensuring continued accuracy and performance over time.
