Transmitters & Sensors Description
Advanced Corrosion Resistance for Sewage & Waste Water
316L Stainless Steel & PTFE Shielding for Harsh Media. Designed specifically as a submersible level transmitter for sewage, this instrument features a hermetically sealed 316SS body construction. To combat the aggressive chemicals found in biogas production and wastewater treatment, we offer an optional PTFE coating. The design includes a removable nose cone that protects the sensitive 316L stainless steel diaphragm from solids and debris, ensuring this anti-corrosion level transmitter maintains its integrity during long-term immersion in industrial waste channels.
Precision Sensing with the Imported GE Core
0.5% FS Accuracy & 20-Pore High-Sensitivity Filter. At the heart of our level transmitters is a high-performance GE sensing element providing a standard 0.5% FS accuracy. To ensure consistent readings in turbulent or silty environments like retention ponds, the sensor utilizes a unique filter with 20 pores. This design maximizes sensitivity while preventing clogging. Combined with a shielded and vented cable that automatically compensates for atmospheric pressure changes via a maintenance-free filter, our hydrostatic level control remains precise regardless of external weather conditions.

What is the best level transmitter for wastewater and sewage measurement?
A submersible level transmitter with a 316L stainless steel diaphragm and a removable nose cone is ideal for wastewater. The nose cone protects the sensor from physical damage by debris, while the 316SS housing resists corrosion. For aggressive sewage, adding a PTFE coating ensures the longest possible service life.
How does lightning protection work in submersible level transmitters?
Quality level transmitters use Dual Arrestor technology to shunt high-voltage surges away from the sensitive GE sensing element. This Lifetime Lightning Protection is essential for sensors installed in open areas like dams, reservoirs, and retention ponds, where equipment is highly vulnerable to atmospheric electrical strikes.
Why is a vented cable necessary for hydrostatic level measurement?
To ensure accuracy, the sensor must compare the liquid pressure against the atmospheric pressure. A vented cable contains a small tube that allows the sensor to “breathe.” Our cables include a maintenance-free filter at the vent to prevent moisture or dust from entering the tube, which would otherwise cause measurement errors or sensor failure.
Can these level transmitters be used in explosive biogas environments?
Yes, our instruments are certified with an Ex d IIC T6 explosion-proof rating. This makes them safe for use in hazardous areas where flammable gases, such as methane in biogas production or wastewater lift stations, are present, ensuring compliance with global industrial safety standards.
What makes a GE-core level transmitter superior to standard sensors?
The USA imported GE piezoresistive core offers superior temperature compensation and long-term stability. Combined with a 0.5% FS accuracy and a 20-pore filter design, it provides higher sensitivity and more reliable data than generic sensors, particularly in applications requiring high-precision liquid level monitoring.
What is the maximum depth for a submersible level transmitter?
While standard sensors are often limited, Instrava’s submersible level transmitters are customizable for ranges up to 200 meters. Combined with a 270-pound tensile strength cable, these units are robust enough for deep well monitoring, dams, and large-scale industrial water storage.
