Product catalog summary
Overview
The Float-11 series by Shenzhen Jiwei Automations Ltd. are float level indicators based on Archimedes' Buoyancy Principle. They are designed to measure fluid levels in vessels by converting changes in resistance into a 4-20mA DC output signal for remote monitoring and control. The series includes models made from various materials to accommodate different fluid densities and chemical properties.

Key Features
  • High-quality plastic reed switches for durability.
  • LED display configurable in horizontal or upright positions.
  • Explosion-proof certification for Flameproof Enclosure and Intrinsic Safety.
  • Ingress Protection rating of IP66/IP67.
  • Materials available: 304, 316L stainless steel, ECTFE/PTFE coatings.

Models
Float-11A Standard
  • Made of 304 or 316L stainless steel.
  • Suitable for most liquids, including petroleum, chemical raw materials, and industrial wastewater.
Float-11P Coated
  • Coated with ECTFE/PTFE for strong corrosive liquids.
  • Used in chemical industry, oil refining, and water treatment.

Technical Specifications
  • Measuring range: 300-6000mm.
  • Medium density: ≥0.5g/cm³.
  • Process pressure: ≤25bar.
  • Temperature range: Process (-20 to 120°C), Ambient (-40 to 70°C).
  • Accuracy: ±5mm/±10mm.
  • Signal output: 4-20mA.
  • Power supply: 18-36V DC.

Jiwei Float Level Indicator Catalog-2

Float Level Indicator Float-11 series are based on Archimedes Buoyancy Principle. Float rises and falls as the fluid level in a vessel change. Due to magnetic effect, as the float moves, the proximal reed switches in chamber are magnetized by permanent magnet in the float and change the status from “open” to “closed”. The resistance value in the sensor changes linearly. The change of resistance value is then converted into 4 ~ 20mA standard DC output signal for remote detection and control. Float-11 series can be made of different materials for fluids with different chemical properties. Jiwei...
