FLOW METER FLOW METERS TDS-100F is a fixed mounted ultrasonic flow meter,and can operate with all HIPEAK instruments transducer. Their electronic enclosures are rated as IP65 (NEMA 4X), thus, can be installed for both indoor and outdoor. ItemPerformance, ParametersAccuracy Better than ±1.0 % Repeatability 0.2% Velocity ±32m/s Measurement Period 0.5S Measurement Principle Transit-time measurement principle Display LCD with backlight. 2x20 letters. Keypad 4x4-key membrane keypad with tactile feedback Input Five channel 4-20mA current inputs for signals such as temperature, pressure, liquid level, and etc.. Accuracy 0.1%. Two of the five input channels are wired to terminal blocks. The remaining three channels are optional. Outputs Analogue output: 4-20mA or 0-20mA current output. Impedance 01kΩ. Isolated OCT output: for frequency output (0-9,999Hz), alarm driver, or totaliser pulse output, ON/OFF control, etc. Relay output 1A@125VAC or 2A@30VDC. For ON/OFF control, alarm driver, totaliser output, etc. Internal Alarm (Buzzer): user programmable. External Alarm Driver: alarm signal can be transmitted to Relay or OCT output terminals to drive an external alarm. RS-232 serial port. Others Capable of offline compensation for flow totaliser, automatic / manual selectable. Self-diagnosis. Automatically record the following information: The totaliser data of the last 64 days / 64 months / 5 years; The power-on time and corresponding flow rate of the last 64 power on and off events. Allow manual or automatic flow loss compensation The instrument working status of the last 64 days Power AC: 220VDC: 8 36VDC or AC7-30V Power Consumption < 2W Work time Continuous Environment Temperature -30-80 Degrees Celsius Environment Humidity 85% RH
