PORTABLE TRANSIT TIME FLOW METER SPECIFICATIONS
|
SCOPE : This specification covers a portable, ultrasonic Transit Time flow meter by Greyline Instruments, Massena, New York / Long Sault, Ontario. This instrument shall provide for non-intrusive flow measurement, indication, totalizing and transmitting of the flow rate in a full pipe.
|
GENERAL |
Each portable Transit Time flow meter shall have the following design features and engineering specifications:
|
A. PERFORMANCE SPECIFICATIONS |
|
Have an accuracy of ±2% of reading in most clean fluid applications. Have repeatability of ±0.5%.
|
|
Operate on clean liquids in full pipes with less than 2% solids or gas bubbles.
|
|
Operate on the following pipe materials: carbon steel, stainless steel, PVC, PVDF, fiberglass, galvanized steel, mild steel, glass, copper, brass and pipes with bonded liners including epoxy, rubber and Teflon.
|
|
Operate on AC/DC power. Include an internal NiMH rechargeable battery with minimum capacity for 6-10 hours continuous battery operation. Recharge and operate with power input of 100-260VAC 50-60Hz.
|
|
B. TRANSDUCERS |
|
Have a dual transmitting/receiving, clamp-on transducers.
|
|
The transducers shall be waterproof and operate continuously at temperatures from -4°F to 257°F (-20°C to 125°C).
|
|
The transducer shall be designed to install on pipes with inside diameter ranging from 2" to 40" (50 mm to 1000 mm).
|
|
Have a 6 ft (2 m) long cable from the transducers to the electronics.
|
|
Shall include manufacturer's recommended sensor coupling compound.
|
|
Shall include stainless steel mounting rack with spring-loaded clamps.
|
|
C. ELECTRONICS |
|
Have a portable, hand-held ABS enclosure plus a padded carrying case containing the flowmeter, sensors and accessories. Total shipping weight shall not exceed 18 lbs (8 kg).
|
|
Electronics shall be designed for continuous operation at temperatures from 32° to 122°F (0° to 50° C).
|
|
Have a built-in 16-key programmer with user-friendly calibration menu.
|
|
Have a backlit graphics display indicating positive and negative flow rates and flow totals, flow graphs, calibration menu, signal strength, battery charge status, date and time.
|
|
Have flow proportional 0/4-20mA output rated to maximum resistive load of 750 ohms.
|
|
Have a built-in 50,000 point data logger, RS232C serial output and connecting cables. Data logger shall support time and date-stamped logging in user-selectable time periods.
|
|
Have automatic signal strength monitoring and indication.
|
|
Have a battery status indicator with automatic low battery shut off and battery overcharge protection.
|
|
D. MANUFACTURER
|
The instrument shall be a Portaflow SE Portable Transit Time Flow Meter by Greyline Instruments Inc., and warranted against defects in materials and workmanship for one year.
