Product Overview
E+H Waterpilot FMX11 Submersible Hydrostatic Level Transmitter
FMX11-CA11GS10
The Waterpilot FMX11 is a high-precision, heavy-duty submersible hydrostatic level transmitter engineered for continuous liquid level and depth monitoring in fresh water, groundwater wells, drinking water reservoirs, and surface water bodies. Featuring an ultra-compact 22mm stainless steel 316L housing, an integrated atmospheric pressure compensation tube with a protective Teflon filter, and international drinking water certifications, this compact dip cell sensor delivers exceptional long-term stability and precise 4–20 mA signal output even in narrow 1-inch pipes and demanding environmental conditions.
The Waterpilot FMX11 submersible hydrostatic level transmitter offers a robust, cost-effective, and highly reliable solution for continuous liquid level measurement in unpressurized tanks, deep wells, water towers, and open water bodies.
Operating on the proven hydrostatic pressure principle, this transmitter converts the liquid column pressure directly into a high-accuracy 4–20 mA current loop output compatible with standard PLCs, RTUs, data loggers, and digital panel meters. Its rugged 316L stainless steel body, combined with a tough abrasion-resistant TPE cable jacket and advanced surge protection, guarantees long-service durability and minimal maintenance requirements in municipal water treatment, hydrological monitoring, and agricultural irrigation infrastructure.
FAQ
Q1: How does the Waterpilot FMX11 account for barometric pressure changes?
A: The extension cable includes an integrated atmospheric pressure compensation tube equipped with a hydrophobic Teflon filter. This design ensures accurate hydrostatic pressure measurement regardless of local weather changes while keeping moisture out of the electronics.
Q2: Is the Waterpilot FMX11 suitable for drinking water applications?
A: Yes, the FMX11 holds multiple global potable water approvals, including NSF/ANSI 61, ACS, KTW, and DVGW, making it completely safe for direct submersion in potable water storage and supply systems.
Q3: Can the FMX11 be fitted into narrow well pipes?
A: Absolutely. With a slim housing diameter of just 22 mm (0.87 inches), the transmitter easily slides into standard 1-inch groundwater wells, guide pipes, or narrow sampling tubes.
Q4: Do you offer custom cable lengths and OEM options for bulk orders?
A: Yes, as a professional automation instrumentation manufacturer, we provide customizable cable lengths, specialized mounting accessories (such as suspension clamps and junction terminal boxes), and flexible OEM/ODM manufacturing solutions to meet your market demand.
