1. Features and applications:
When measuring saturated or superheated steam, we first use a steam vortex flowmeter with temperature and pressure compensation, which can measure flow, pressure, and temperature at the same time. The instrument device can withstand a maximum temperature of 350°C. Since the volume of steam will change with temperature, in order to measure accuracy, it is possible to add temperature and pressure compensation types so that the display unit can use mass units. When the temperature changes, the mass is constant. The output can be 4-20MA current output, Modbus communication, etc., which can be effectively connected to the control system for remote monitoring. The vortex flow meter for steam application has integrated temperature and pressure compensation and split temperature and pressure compensation types, plug-in temperature and pressure compensation, no parts in the middle of the sensor, long service life, easy maintenance, and low maintenance cost. It occupies an important position in our daily flow measurement of compressed air, liquefied petroleum gas, natural gas, steam, etc. The instrument can also measure non-corrosive uniform liquids such as water, oil, thermal oil, beer, and beverages.

PV Unit |
Option: L/s, L/m, L/h, m3/s, m3/m, m3/h, Nm3/h, USG/h, Kg/s, Kg/m ,Kg/h ,t/s, t/m, t/h Default = m3/h; define the unit of the flow rate L (liter), h(hour), t(ton), s(second) , m(minute) |
USG/s |
USG/m |
|||
|
PV Decimal |
Option: 0 1 2 3, default = 1 Define the decimal point position of the flow rate. |
|||||
|
Flow Range |
Float point： 99999999.00-0.00 m3/h, default = 100.0 m3/h When the instantaneous flow rate reaches this set value, the output current is 20mA. Changing this parameter will affect current output, high and low flow alarm, etc. NOTE: When you modify the flow range, please pay attention to the flow range unit. You can also modify the flow range unit here. |

Low Flow Cut |
Float point: 9.90 ～ 0.00 %, default = The set value is a percentage. of flow range |

|
Low Alarm |
Float point: 99.00 ～ 0.00 % ,default = 0.0 % This value is a percentage of flow range. for example, if this value is setup to ten(10), then Equivalent to ten percent(10%) of flow range. If the Absolute value of instantaneous flow < (flow range × 10%), then the reansmitter will output the low alarm signal, and the contact of low alarm will close. |
|||||
|
High Alarm |
Float point: 99.00 ～ 1.00 % ,default = 90.0 % This value is a percentage of flow range. for example, if this value is setup to ten(10), then Equivalent to ten percent(10%) of flow range. If the Absolute value of instantaneous flow > (flow range × 10%), then the reansmitter will output the high alarm signal, and the contact of high alarm will close. |

5. RFQ:
Q1. What is the difference between a vortex flow meter for steam application and an orifice flow meter?
A1: The vortex flow meter has a simple structure, low total purchase cost, and high precision. The orifice flow meter has a body, a three-valve group, a condenser, a differential pressure transmitter, etc. There are many components, and the installation and maintenance of the vortex flow meter without temperature and pressure compensation are simple, and the maintenance cost is low.
Q2. Are you a manufacturer?
A2: Yes, our factory started in 2002 and has more than 20 years of R&D and production experience.
Q3. How is your delivery time?
A3: We have a strong inventory of raw materials, standard type: within 100 pieces, the production time is expected to be 6-7 working days after confirming the order. Non-standard type: According to the order specifications and quantity, our sales representative confirms the order production time.
Q4. What is your minimum order quantity?
A4: Our minimum order quantity is 1PCS.
Q5. How do you ensure good product quality?
A5: We have a complete quality control system; all our products are fully inspected by IQC, OQC departments before shipping to customers.
Q6. How long is your quotation valid?
A6: Our normal quotation is valid for 1 month.
Q7. Can you accept OEM brands?
A7: Yes, we can accept OEM brands without additional charges.
Q8. How long is your product's warranty period?
A8: Our product warranty period is 24 months,
