Water Specialties Propeller Meter Specification TR16 Solid State Indicator-Totalizer-Transmitter, Current Output, Two Wire Circuits McCrometer, Inc., 3255 W. Stetson Ave., Hemet, CA 92545 Tel: 951-652-6811 Fax: 951-652-3078 Web Site: www.mccrometer.com PREPARED BY: [ENTER COMPANY AND CONTACT INFORMATION HERE] [ENTER ADDRESS] [ENTER CITY, STATE & ZIP] Phone: [ENTER PHONE] FAX: [ENTER FAX] e-mail: [ENTER E-MAIL ADDRESS] TRANSMITTER shall be encased in a sealed housing conforming to NEMA standards. It shall provide a solid state, optically coupled pulse output and a loop powered current output to drive the associated instrument(s). The unit shall be a WATER SPECIALTIES MODEL TR16 transmitter with a 4-20 mADC output at a maximum instrument scale of __________. Also available, if desired, is a pulse output of _________. The enclosure shall be made from injection molded 20% glass filled engineered grade of thermoplastic. It shall attach directly to the propeller meter head with screws having holes for seal wires and be protected with an o-ring seal. OUTPUT shall be in direct proportion to the flow through the meter at the above pulse rate and current output. The signal shall be produced by a solid state printed circuit card and optic switch. The P/C card shall be protected with a dip application of clear sealer and run through an ultra violet light procedure to verify no voids occured in the coating. The unit shall be powered by an external 12-30 VDC power supply (Water Specialties P/N IN36-1) wired in a loop with the current output. The 4-20 madc output shall not change or require any field adjustments with the varying voltage of the power supply. The TR-16 must also meet the following requirements: Accuracy: True two wire current output, + 0.5% of full scale. Two wire isolated pulse output, + 2.0% of actual flow. Temperature: 32° to 140° F External power supply: 12-30 VDC Polarity protection: 35 VDC pulse output reverse voltage. MA output non-polarized, current is rectified internally. Output load: pulse rate, 60 MA @ 18 V max. current output, 900 ohms or less. INDICATOR-TOTALIZER shall have a full 4" diameter indicator dial having a range of 0 to ________ (specify indicator range and units) and shall be equipped with a six digit, straight reading type totalizer with black number wheels at least 1/4" high. The totalizer shall read in units of _______ (specify totalizer units) and shall have a test hand to check the accuracy of the indicator. The indicator drive mechanism shall be temperature compensated, so the indicator hand shall be accurate and linear within + 1% at all points on the dial when the unit is operated within the temperature range of 32°- 140° F. The unit shall be equipped with change gears to facilitate easy change of registration without removing pressure from the line or removing the transmitter base from the meter tube. The indicator-totalizer shall be protected by an o-ring sealed bonnet made from injection molded 20% glass filled engineered grade of thermoplastic. The bonnet shall be attached to the transmitter by screws located under the hinged lid, which has a padlock hasp. PARTS & SERVICE: Supplier must have test facilities, spare parts, personnel to maintain, instruct, train or whatever is necessary to assure transmitters will be maintained throughout the guarantee period. ---------- McCrometer, Inc. 3255 W.
