66 -- PORTABLE TIDE GAGE MEASUREMENT SYSTEM SOL N623067133KTRNIA N6230697QC002 DUE 071897 POC Contract Specialist, S.R. KEEL, (601) 689-8368, FAX 601 689 8392 The Naval Oceanographic Office is seeking information concerning potential sources, including manufactures, dealers, and/or distributors, of currently available commercial off the shelf type submersible portable tide gauges. This synopsis is issued for information and planning purposes only and IS NOT to be construed as a solicitation or any commitment by the Government. Minimum Government requirements are as follows: The tide gauge units shall be deployable from the shore in salt water depths from 0.5 to 20 meters sensor head shall be capable of deployment of a minimum of fifteen (15) meters from the recording device or RS-232 downloading port. The tide gauge units shall measure salt water pressure to an accuracy of (+)(-) 2 cm whichever is higher. The system shall include automatic compensation for changes in water column density due to salinity, water temperature and barometric pressure. The units shall be capable of storing and displaying pressure in one (1) centimeter increments. The units shall be capable of measuring tidal ranges of 0 to 15 meters. The unit's sample interval shall be user selectable with a minimum of the following internal settings: two (2), five (5), fifteen (15) thirty (30) and sixty (60) minute settings. The unit's integration time of each measurement shall be user selected with a minimum of the following time settings: thirty (30) seconds and one (1), two (2) and five (5) minutes. All data shall be stored in a non-volatile form. Each unit shall be capable of storing a minimum of six (6) months of collection data having a sample interval of fifteen (15) minutes. The stored data shall also contain all user selectable parameters including tide gauge unit used to collect data. All stored data shall be available via an RS-232 interface at the tide gauge unit. Data Retrieval shall not require disturbing the tide gauge's sensor head original placement. Any external devices, other than a government furnished laptop computer, required to setup and/or retrieve data shall be provided by the contractor. The tide gauge units shall have a means of displaying tidal height in centimeters during the deployment of the unit to a government furnished laptop computer. All software required to perform these functions shall be provided by the contractor. All software will need to be compatible with Microsoft Windows 95 and run in the Windows GUI environment. Software will, as a minimum, provide the user with time tagged depths reading at the selected interval, statistical analysis package to include mean tide depth, tide range, and mean low water and mean high water. Government furnished computer is a Pentium based laptop running Windows 95 with DB 9 serial interface and color VGA screen. The operating temperature range of each unit shall be from minus ten (10) to plus (=) fifty (50) degrees Celsius with a humidity of 100% condensing. Submerged gauges that include vented atmospheric correction shall include a user refillable desiccant cartridge. Desiccant cartridge shall be refillable with loose package granular desiccant available from local sources. Desiccant shall be sufficient to ensure correct gauge operation in the above specified ranges for a period of three (3) months. System shall be provided with initial desiccant, the Government will provide additional desiccant as required. The deployable gauge units and all equipment setup and installation of the units shall either be designed or packaged to withstand being dropped a distance of up to thirty (30) inches without damage to the equipment. Each unit shall include sufficient DC power, external of either 12VDC or 120AV/220 AC source, to function fully for a minimum of sixty (60) days with the unit set for a sample rate of 15 minutes, and an integration time of five (5) minutes. A connector shall be provided for connecting an external battery or alternate power source of either 12 Volts DC, 110V olts AC or 220 Volts AC. System shall include external batteries as required. Batteries shall be of a rechargeable type and the units shall be supplied with battery charges capable of charging units using either 120VAC or 220 VAC. Provide weight, height, depth, length of unit including the deployed sensor, above water interface, and below water surface. This does not include any solar panels or batteries. Provide information regarding unit Telemetry capabilities and its communication capabilities and if this is a separate item entirety with its own price and if the system has the ability to accept contractor provided or other various telemetry modules that will transmit tidal data to central data collections points. The modules should be addressed on system capability such as ARGOS, Phone (land line and Cellular) and Radio (VHF, UHF, or HF). Contractor shall provide a listing of telemetry sub-systems capable of interface with contractor's tide gauges/systems. Commercial contractors who intend to respond to this notice are to provide at a minimum two (2) complete sets of brochures (pictorial if available) on the unit(s) available. The brochures of specific systems available should be marked as well as the pertinent information relevant to model number meeting the requirements, size, specifications and capability, power supply requirements, a list of unit components and or enhancements currently available, commercial warranty information, payment terms, maintenance requirements and all other pertinent data on units along with contractor price list(s) available. It is requested interested parties also provide a brief statement regarding spares available on units and how the units are supported through out their life span, etc. A demonstration of some of the unit(s) may be required at a later date. The NAVO office IS looking for contractors with commercial off the shelf type tide gauge meeting the criteria contained herein or meeting the criteria with minor modification(s). Contractors are requested to provide the name of the company submitting response and manufacturer of the product, point(s) of contact, phone and fax numbers. Contractors are requested to include in their response the following Company information relative to their size structure and capabilities (i.e., company name, address, telephone number, internet address, if company is a manufacturer or distributor, how long the firm has been in business selling this type of equipment, parent company name and address, if applicable, facilities information, business size (i. e., large, small, or small disadvantaged business, woman owned company, etc.) No additional technical information, other than published in this synopsis, is available at this time. All interested parties and responses to this notice are to be submitted to the Naval Oceanographic Office, Contracts Division, Code N412, Attn Suzanne Keel, Stennis Space Center, MS 39522-5001, by July 18, 1997 (FAX or Mail).
