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.
Specifications are subject to change without
notice.
