digital target flow meter/base oil flow meter
SBL target flow meter can measure widely used in gas,liquid,steam,petroleum industry,chemical,engineering,energyindustry,food industry,environmental protection,and water conservancy etc. Nowadays,we focus on both domestic and international market.The flow meter with high veliability and durability,convenient installation and maintenance,competitive price.it no moving part, high sensitivity,good anti-vibration and interference.now,our target flo wmeters have a new breakthough,that is,our flow meter no zero drift.it can automatically be cleared the zero by itself.

SBLdigital flow meter can widely used a variety of size pipeline and a variety of measurement media
SBL flowmeter mainly consists of measurement tube (casing), stress element (target plate), sensing elements (force transducer, pressure transducer and temperature transducer), transition part (adjusted according to temperature and pressure), and accumulation calculation, display and output part. Refer to the following figure for the structure:
Refer to Fig.1 for operation schematic of model SBL target flowmeter with digital display. The stress element (target plate) is placed at center of measurement tube (instrument body) coaxially, with rigid connection with transducers. When measured medium flows at certain velocity (m/s), this medium has certain momentum that directly acts on the stress element (target plate). Due to rigid connection between stress element and transducer, the transducer is subject to direct force F generated by fluid momentum. This force is related to flow velocity V, medium density ρ and area of target subject A to force as follows:
In which:
F——force on target plate
CD——resistance coefficient
P——fluid density, kg/m3
V——fluid velocity, m/s
A——area of target plate subject to force, m2
Through derivation and conversion, the flow is calculated as follows:
In which
Qm, QV---mass flow and volume flow respectively (kg/h, m3/h)
α----flow coefficient
D----inner diameter of measurement tube, mm
β----diameter ratio, β=d/D
d----target plate diameter, mm
Other symbols are the same before.
Force on target plate is converted to electric signal by the force transducer. This signal is amplified by pre-amplification and processed by AD conversion and computer, to provide corresponding flow and total quantity. Operating principle is shown as follows:
1. Measurement tube; 2. Target plate; 3. Target rod; 4. Transducer; A. Strain-meter
