Description of ASTM-F2044 2009ASTM F2044 - 09Standard Specification for Liquid Level Indicating Equipment, ElectricalActive Standard ASTM F2044 | Developed by Subcommittee: F25.10 Book of Standards Volume: 01.07 ASTM F2044Abstract This specification covers the requirements for electrical liquid level indicating equipment for shipboard low pressure and high pressure tanks containing freshwater, feed water, potable water, seawater, wastewater, diesel fuel, lubricating oil, contaminated oil, refrigerants, JP fuels, and various other fluids. Application includes compensating tanks in which the equipment must locate the interface. Each liquid level indicating equipment shall consists of one or more sensing devices; primary indicator panel assembly; and flexible interconnections, auxiliary indicator panel assembly, and portable indicator panel assembly, when needed or required. The level sensing techniques include: admittance and impedance, magnetic float, differential pressure, time domain reflectometry, capacitance, resistance tape, static pressure, radar, and ultrasonic sensing. The most common types of process media and the specified pressure range and display for liquid level indication are given. Materials for the sensing devices and wetted pans shall be selected for long-term compatibility with the process medium. Physical property requirements include: (1) enclosure, (2) liquid level indicating equipment mounting, (3) external configuration, (4) electrical connection, and (5) size and weight. Critical service life and performance requirements shall be specified in the acquisition requirements. The following performance characteristics and environmental exposures may or may not be important to the intended application: accuracy, response time, repeatability, hysteresis, insulation resistance, specific gravity, fluid conductivity, tank wall proximity, inclination, spike voltage, salt spray, vibration, shock enclosure, dc magnetic field, electromagnetic interference, immersion, and supply line voltage and frequency variation. Inspection requirements specified are classified as (1) first article test and (2) conformance test. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. 1. Scope 1.1 This specification covers the requirements for electrical liquid level indicating equipment for shipboard low pressure and high pressure tanks containing freshwater, feed water, potable water, seawater, wastewater, diesel fuel, lubricating oil, contaminated oil, refrigerants, JP fuels, and various other fluids. Application includes compensating tanks in which the equipment must locate the interface. 1.2 Each liquid level indicating equipment typically consists of the following components: (a) One or more sensing devices; (b) Flexible interconnections, if needed; (c) Primary indicator panel assembly; (d) Auxiliary indicator panel assembly, when required; and (e) Portable indicator panel assembly, when required. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. Where information is to be specified, it shall be stated in SI units. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.5 Special requirements for naval shipboard applications are included in the Supplement to this standard.
