Product Overview
Continuous Side-Entry Level Sensing
Engineered for tanks with limited top clearance, high overhead piping, or specialized side process nozzles.
The FlowDo Side Mounted Level Transmitter attaches directly to the side of storage tanks or external bypass chambers via ANSI/DIN flanges. Utilizing a precision magnetic float assembly or continuous probe sensor, the instrument follows the liquid interface height and transmits real-time level values without requiring overhead tank access.
This design is particularly advantageous on tall storage silos, indoor vessels with ceiling obstructions, agitating tanks with top mixers, and fuel or chemical tanks with existing side nozzles. The hermetically sealed electronics head outputs an isolated 4–20 mA loop signal for integration into PLC/SCADA systems.

Side Mounted Level Transmitter FAQs
Common technical questions regarding side-mounted continuous level measurement.
What is a side mounted level transmitter?
It is an industrial instrument installed on the side nozzle of a tank or external bypass chamber to provide continuous measurement of liquid level (0–100%).
When should side mounting be used instead of top mounting?
Side mounting is ideal when top tank access is restricted by ceiling clearance, agitators, mixers, heating coils, or when tanks have pre-existing side nozzles.
Is it a continuous measurement device?
Yes. A side-mounted transmitter provides continuous 4–20 mA proportional feedback across the calibrated span, unlike a level switch which only detects a single point.
What process connections are available?
Standard ANSI 150#/300# flanged connections (1.5", 2", 3", 4") and heavy-duty threaded process connections according to customer nozzle requirements.
Can it handle high temperatures and pressures?
Yes, stainless steel SS316 wetted construction supports operating pressures up to 16 bar and process temperatures up to 200°C with optional cooling extensions.
Can it connect to PLCs and digital level indicators?
Yes, standard 2-wire 4–20 mA current loop output connects directly to industrial PLCs, DCS systems, SCADA RTUs, and FlowDo digital indicators.
