Separate Fixed Calorimeter / LRC-2000S

LRF-2000S User Manual
LRC-2000S is wall-mount economical ultrasonic heat/cold meter. It is comprised of wall-mount ultrasonic flow meter and a pair of temperature sensors PT100.

Features

l High Accuracy measuring
Linearity: better than 0.5%, Repeatability: better than 0.2%, Accuracy: better than ±1%
l Wide measuring range
Several types transducer for selection, measuring pipe size from DN15mm to DN6000mm
l High Reliability
Adopt low voltage, multi-pulse technology to improve accuracy, useful life and reliability
l Strong Anti-interference
Dual-balance signal differential receiver/driver circuit to avoid interference of converter,TV ower, high voltage line etc.
l Powerful Recording Function
Automatically record the following data:
1.The totalizer data of the last 512 days/128 months/10 years
2.The time and corresponding flow rate of the last 64 times of power on and off events
3. The working status of the last 32 days
l With the clamp on ultrasonic temperature transducer
