No. It's certainly a possibility, don't get us wrong, but it just doesn't happen. Part of that reason is that we never recommend this type of level transmitter to applications that would involve sticky or otherwise strong enough build-up to overpower the float. Another part of the reason is that we have allowed enough space between the float and the stem to let most objects pass through. The weight of the float is also important, and prevents sticking.

Could it happen? Yes. Does it happen? No. With over 10,000 units installed, some for close to a decade, we have never received a call about build-up, or sticks, or any other object sticking the float.

Yes. We have two models that offer a voltage output - the RPM and the RP. Each is a resistive chain sensor, meaning they use a series of reed switches to change the resistance of the sensor. The voltage output is directly proportional to the level in the tank.
Our most accurate float level transmitter, the MPX, compares very well to an ultrasonic sensor's resolution and accuracy. It's resolution is ±4mm and it's accuracy is 0.05% of full scale. Our ultrasonic sensors are accurate to 0.25% full scale.
No. Our continuous float level transmitters are designed for very harsh environments where a robust steel design is essential. They're available in 316L stainless steel and 304 stainless steel.
Yes. Our MPX continuous float level transmitter can measure two level simultaneously. You'll need to order it with the second float and verify the specific gravity/density of your liquids. You'll get an MPX with two floats, one that will float on the top of the oil, and the other that will float at the oil/water interface.
